Worked: (newest version of Blender that worked as expected)

Short description of error
Blender 2.90 Alpha work for a while make crash guide.

Exact steps for others to reproduce the error

between belly through tail.
Knife drag then select 2 or 3 vertex then push the 'M' key
From Vertex click to Face
Select Face
also Add materials and rename to "Extra Select" on materials
Change color.
(leave editmode)

Crash might occur, hard to reproduce.

@Kent-Davis : I feel your pain. And I do believe you are experiencing crashes.

But: I dont think anything changed since reporting {#77793}?
No example file, no steps to reproduce, no nothing.

I can only repeat myself:

In #77793#952827, @lichtwerk wrote:
@Kent-Davis : unfortunately, we cannot afford to work randomly "any minutes, any hours" to blindly hunt down a bug.
We need your help here. Save often, If a crash occurs, immediately stop and try to reproduce what you just did to see if you can get it to crash again.
In the end you should have a file with clear instructions for devs what they have to do to reproduce your crash.

A guideline for making a good bug report can be found at https://wiki.blender.org/wiki/Process/Bug_Reports

If 2.90 is still too unstable for daily production work (it is still early in the release cycle), please use 2.83 instead.

Thx for reporting, but I think we have to close this (feel free though to comment again if you have found exact reproduction steps, and we can always reopen this report, thx)

I get me mad why you put invalid too fast!

No file require. Blender 2.90 Alpha work without save not matter cause crash guide. Many times crash.

Then please help us fix the crash by providing steps to reproduce, please.
Or are you saying blender crashes when you just open it? No.
Does it crash when you go into editmode on the default cube? No
It seems to crash when

add, remove vertex, edge and etc

How are you adding these? Extruding?

@Kent-Davis : Dont get me wrong, stuff you have reported helped numerous times fixing an issue, but you need to help us in a way that is reproducable.

between belly through tail.
Knife drag then select 2 or 3 vertex then push the 'M' key
From Vertex click to Face
Select Face
also Add materials and rename to "Extra Select" on materials
Change color.
Without step by step. Any where and any select.

Note: I tried randomly and indeed ran into following assert after doing above steps [leaving editmode]

BLI_assert failed: /blender/source/blender/blenkernel/intern/customdata.c:2252, CustomData_get_layer_index(), at 'customdata_typemap_is_valid(data)'

I have seen this assert before in #77776 (Blender 2.83 crushes after join meshes.)

This is still not really reproducable, just saying.

I see it is where I made some changes. so will dive deeper. The issue is related to a hack we introduced d98ae27f02 to fix another issue.

Open the application Blender 2.90 Alpha appear then Command + O then push the ESC key then Control+Command+F 2 times then Command+O then esc cause crash guide while I am do fastest.

I was able to reproduce it with RPanel2_repro.blend open file and keep switching between object and edit mode. First time it took me a minute but I was able to reproduce. Will have a go at it next week.

The assert is telling the developer that the mesh custom data is in an incorrect state. So somewhere in blender we miss a call to CustomData_update_typemap

@ideasman42 during drawing of a mesh just after leaving edit mode we can get an assert (CustomData_update_typemap isn't up to date). I expect that there is a missing call to CustomData_update_typemap somewhere in the codebase. Note that the new threading in drawing seems seems to point it out, although it is still very hard to reproduce.

Does this ring a bell that CustomData_update_typemap isn't up to date when starting drawing?

Ah I see that the tangent normals is changing the typemap! what used to be in the main thread, but now is inside a thread so other threads may have a synchorization issue here.
extract_tan_ex can perform a CustomData_free_layers, BKE_editmesh_loop_tangent_calc or BKE_mesh_calc_loop_tangent_ex this should be moved to the main thread.
