System Information
Operating system: Windows-10-10.0.19043-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 3080 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 526.47

Blender Version
Broken: version: 3.4.0, branch: blender-v3.4-release, commit date: 2022-12-06 18:46, hash: a95bf1ac01
Worked: (newest version of Blender that worked as expected)

Short description of error
When applying an boolean modifier (solver: exact, materials: index based) blender will crash when attempting to texture paint the newly added cut hole. This issue appears also on current daily builds. On blender 5.0 alpha it doesn't crash but doesn't paint either.
A file for reproduction and the crash file are attached.
Could be related to previous bug report: https:*developer.blender.org/T99191
Which should have been fixed already (but the issue came back or never got fully fixed): https:*developer.blender.org/rB5723bf926dcb387224dd0de2a4c562bc316e8edc

Exact steps for others to reproduce the error
Open attached .blend file and texture paint inside cylinder hole of the cube or:

add object with a material (image texture plugged into shader)
add second object without setting a material
add bool modifier set to solver exact and materials to index based
apply modifier
texture paint inside boolean "hole"
blender will crash soon

Potential User based fixes

setting solver mode to fast
using the same material on both objects before applying modifier
setting materials to transfer in modifiers settings
edit mode: select all faces and reassign material after modifier got applied (note: the material will stay the same (the correct material got automatically applied when applying modifer) but blenders internal data handling will get fixed by that resulting in no crash, even though material stays the same on frontend side)

Hi, thanks for the report. Crash is is same as reported in #103544 (Texture Painting after boolean crash blender)
I'll close this report as duplicate. Will open a fresh report for " it doesn't crash but doesn't paint either."
