@PratikPB2123 I removed this line of code and blender still closes.
And I don't understand why there are only 'Linear' and 'sRGB' among the options.
Here is the setting:

Ah, ignore the python traceback then. Results were taken from the lite build

crash.txt doesn't contain any info. Though there is python backtrace of add-on. Issue might be related to add-on.
What error did you get in event viewer after the crash?

Results were taken from the lite build - - - crash.txt doesn't contain any info. Though there is python backtrace of add-on. Issue might be related to add-on. What error did you get in event viewer after the crash?

event viewer

what is an eventviewer? eventvwr.msc? There are no blender errors in eventvwr.msc.

blender closes when i call the function mesh.from_pydata(verts, (), faces):
29adfaffa0/io_scene_xray/formats/ogf/imp/lod.py (L78)

But blender 3.4.1 does not have this error. I have imported the same files.

Here are the vertices and polygons that are causing blender to close:

@Pavel_Blend : does this (modified from the shipping template) Addon also cause crashes for you?
It uses the same verts and faces and seems to have no issues here (also mesh.validate() seems to be fine)

-- it does have double faces though (not sure this is intended?)

@lichtwerk script from 107168.blend works without errors. The object is created.

it does have double faces though (not sure this is intended?)

In a mesh, polygons have normals that point in opposite directions. And polygons are built on vertices that have the same coordinates. But technically, these polygons are not double because they have different vertex indices. This is by design so that the object is not transparent when the Backface Culling mode is enabled.

So it does not seem to be that specific geo, can you isolate more which python call(s) cause the crash?

I imported another file and the error appeared elsewhere in the code:

https://drive.google.com/file/d/1toZ70GcRbQTfd6yarCHyKIzggbdQn5aj/view?usp=sharing

Now the closure happens on the bpy.data.objects.new function.

Because blender closes and doesn't print the error details, I can't figure out what's causing the crash. Every time it crashes in different places of the addon.

Here is the crash file:

This one does not crash in 3.6, right?

There were many backports for 3.5.1, can also check if it still crashes with all those backports in...

@lichtwerk probably the problem is elsewhere.

I imported this file in 3.6.0 and blender crashed:

@lichtwerk I don't know what is causing the crash so I can't create a short example.
From the files blender.crash.txt, blender_debug_output.txt, blender_system_info.txt can you determine where to look for the error?

When I remove the code that creates the vertex colors the error goes away. But when I created the short example using vertex colors the error didn't appear.

I can't reproduce the error without the addon.

Have you tried swapping the order of vertex color creation and me.from_pydata in your Addon as well?

@lichtwerk in the addon without edits everything was already correct. I made this mistake by accident in a short example.

@lichtwerk , I'm not very confident about confirming this.
Initially crash was in the tbb module and now its occurring in CurveMapPoint_location_set function.
Also: this report involves python script plus different extension file. Its not clear to me at least whether python script is faulty or a function in blender is responsible for the crash.

Worked: (3.4.1)

This was not crashing earlier so maybe we could find the cause from the commit history.

What do you mean by "different extension file"?

I added some assertions of the value of as_pointer() into the latest script and have created a simplified script showing what appears to be the issue. I'm on Windows 10 and get the same results in 3.5.1 and 3.6.0a 2023-05-01 0652945dbda7 for all scripts in this comment.

import bpy

me = bpy.data.meshes.new('')
uv = me.uv_layers.new(name='UV')
uv_name = uv.name
uv_pointer = uv.as_pointer()

col_1 = me.vertex_colors.new(name='Col 1')
col_1_name = col_1.name
col_1_pointer = col_1.as_pointer()

uv_from_mesh = me.uv_layers[uv_name]

print("UV Layer names:")
print(uv_name, uv.name, uv_from_mesh.name, sep=", ")

print("Vertex Color names:")
print(col_1_name, col_1.name, sep=", ")

print("UV Layer pointers:")
print(uv_pointer, uv.as_pointer(), uv_from_mesh.as_pointer(), sep=", ")

print("Vertex Color pointers:")
print(col_1_pointer, col_1.as_pointer(), sep=", ")

# Fails
assert uv.as_pointer() == uv_from_mesh.as_pointer()

Example prints in the console:

UV Layer names:
UV, Col 1, UV
Vertex Color names:
Col 1, Col 1
UV Layer pointers:
2156778674184, 2156778674184, 2156778674304
Vertex Color pointers:
2156778674184, 2156778674184

Getting "Col 1" from uv.name shouldn't be happening, and uv.as_pointer() should not equal col_1.as_pointer()

If you add two uv layers, uv.name erroneously gives "Col 1" and uv2.name erroneously gives "UV":

import bpy

me = bpy.data.meshes.new('')
uv = me.uv_layers.new(name='UV')
uv_name = uv.name

uv2 = me.uv_layers.new(name='UV2')
uv2_name = uv2.name
assert uv.name == uv_name
assert uv2.name == uv2_name

col_1 = me.vertex_colors.new(name='Col 1')

# "Col 1"
print(uv.name)
# "UV"
print(uv2.name)
# Fails
assert uv.name == uv_name
# Also fails
assert uv2.name == uv2_name

The issue can also be reproduced by using the attributes API directly:

import bpy

me = bpy.data.meshes.new("")
attributes = me.attributes

uv = attributes.new("UV", 'FLOAT2', 'CORNER')

# Creates the same attribute as `me.vertex_colors.new(name="COL")`
col_1 = attributes.new("COL", 'BYTE_COLOR', 'CORNER')

# "COL"
print(uv.name)
# "COL"
print(col_1.name)

# Fails
assert uv.as_pointer() != col_1.as_pointer()
I added some assertions of the value of `as_pointer()` into the latest script and have created a simplified script showing what appears to be the issue. I'm on Windows 10 and get the same results in 3.5.1 and 3.6.0a 2023-05-01 `0652945dbda7` for all scripts in this comment. ```py import bpy me = bpy.data.meshes.new('') uv = me.uv_layers.new(name='UV') uv_name = uv.name uv_pointer = uv.as_pointer() col_1 = me.vertex_colors.new(name='Col 1') col_1_name = col_1.name col_1_pointer = col_1.as_pointer() uv_from_mesh = me.uv_layers[uv_name] print("UV Layer names:") print(uv_name, uv.name, uv_from_mesh.name, sep=", ") print("Vertex Color names:") print(col_1_name, col_1.name, sep=", ") print("UV Layer pointers:") print(uv_pointer, uv.as_pointer(), uv_from_mesh.as_pointer(), sep=", ") print("Vertex Color pointers:") print(col_1_pointer, col_1.as_pointer(), sep=", ") # Fails assert uv.as_pointer() == uv_from_mesh.as_pointer() ``` Example prints in the console: ``` UV Layer names: UV, Col 1, UV Vertex Color names: Col 1, Col 1 UV Layer pointers: 2156778674184, 2156778674184, 2156778674304 Vertex Color pointers: 2156778674184, 2156778674184 ``` Getting "Col 1" from `uv.name` shouldn't be happening, and `uv.as_pointer()` should not equal `col_1.as_pointer()` --- If you add two uv layers, `uv.name` erroneously gives "Col 1" and `uv2.name` erroneously gives "UV": ```py import bpy me = bpy.data.meshes.new('') uv = me.uv_layers.new(name='UV') uv_name = uv.name uv2 = me.uv_layers.new(name='UV2') uv2_name = uv2.name assert uv.name == uv_name assert uv2.name == uv2_name col_1 = me.vertex_colors.new(name='Col 1') # "Col 1" print(uv.name) # "UV" print(uv2.name) # Fails assert uv.name == uv_name # Also fails assert uv2.name == uv2_name ``` --- The issue can also be reproduced by using the attributes API directly: ```py import bpy me = bpy.data.meshes.new("") attributes = me.attributes uv = attributes.new("UV", 'FLOAT2', 'CORNER') # Creates the same attribute as `me.vertex_colors.new(name="COL")` col_1 = attributes.new("COL", 'BYTE_COLOR', 'CORNER') # "COL" print(uv.name) # "COL" print(col_1.name) # Fails assert uv.as_pointer() != col_1.as_pointer() ```

Thx digging deeper @Mysteryem ! Thx to that I can say that the Assert was introduced with 6c774feba2 (assume the same is true for the crash)

Indeed, I do believen #107500 has the same roots.

After looking into it some more I'm fairly certain this is indeed a duplicate of #107500 , so I close this one.
