I don't have Blender as a Python Module, so I can't try that.
Can't repro for background mode using Blender 3.6/4.1 on Linux. I added
bpy.ops.wm.save_as_mainfile(filepath='test.blend')
to the bottom of my above script, saved it as a.py, and…
The length appears to be 0 only if the object is in edit mode. I get the expected length in object mode. Not sure if this is intentional.
This works for me.

bpy.ops.object.select_all(action='SELECT')
bpy.ops.object.delete()
bpy.ops.object.select_all(action='DESELECT')

When you add or remove a color attribute, generally any existing references to color attributes may become junk (pointer is invalidated). Your workaround avoids this problem by holding onto names…
Just looking at [MeshFromGeometry::create_colors](6a9d2212e4/source/blender/io/wavefront_obj/importer/obj_impor…
Simpler example: Take this OBJ file
v -0.004936 0.000000 1.013093 1.0000 0.4235 0.0000
v 1.995063 0.000000 1.013093 1.0000 0.8470 0.0000
v -0.004936 0.000000 -0.986907 1.0000 0.4235…Nevermind, I managed to repro. I've attached a Test.obj. If o obj is inserted on line 796, the vertex colors are broken. If it is inserted on line 797 instead though, it doesn't break.

Can you attach an OBJ file for testing?

The "Vertex Color" node was renamed the "Color Attribute" node (in 3.2 IIRC).
The effect you see is actually from a small bug in the script. start aliases obj.rotation_quaternion, so you are actually changing start in the loop.
start = obj.rotation_quaternion #…I don't what Flip Quats (Alt F) does. I tried it and it appears to do nothing. But I don't think any operator you run after the fact could fix this; the information about which way you rotated is…
@dr.sybren Starting from the default cube, view it from the top in object mode and hit R to start rotating. Spin around one full rotation counter-clockwise. It goes from 0 degrees to 360 degrees.…
Note that this is inconsistent with Eulers, which work as expected. If you spin the bone around a full revolution in Euler mode you go 0° -> 360°. The equivalent for quaternions would be to go 1…
