There are 2 problems:

When selecting object CC_Base_Body, switching to Edit mode and inside edit mode switching to Face select mode, blender crashes.
In edit mode selected vertices can't be viewed as ther is no slection visible.

As I've found, both problems could be fixed if after opening file and selecting CC_Base_Body, switch to "Shading" workspace and just save/ reload file. But on larger files with more number of materials it doesn't work.

Exact steps for others to reproduce the error

Open attached file
Select object CC_Base_Body
Switch to Edit mode
Select any vertices with block selection - no visible changes in vertices presentation
Switch to Face select mode - blender crashes

Can confirm the crash in 3.6 (4.0 seems alright here).

Mesh seems alright with mesh.validate() it only gives some weight problems, afterwards the same operation still crashes.

Crash only happens when selecting when x-ray is on.

@ChengduLittleA : could you check which commit fixed this? ( so we can add it to #109399 )

@lichtwerk I'll try but no guarantee... 😅 Likely one of the fixes in #109545

Since the fix is not easily backportable, 82ca3d3604 might just get reverted in 3.6, see also #110925 and #109432
