System Information
Operating system: Windows-10-10.0.19044-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 2080 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 536.23

Blender Version
Broken: version: 3.6.4, branch: blender-v3.6-release, commit date: 2023-09-25 13:24, hash: 21bfc5e7fe3f

Short description of error
I have searched previous bug reports and found bug reports that had fixed this issue around 5 years ago:
" Trying to edit mesh crashes Blender #56776, Crash entering edit mode #56932 ".
I have downloaded meshes from these bug reports and they did not produce crash anymore, as expected as for being labeled as Resolved.
However with this mesh, latest stable LTS version as well as 4.0 beta crashes when trying to go to edit mode. Also going to the Cycles interactive rendering seems to crush the program but not every time (I can not reproduce the rendering crash just with this object in the scene and I can when this object is part of the bigger scene, but even then not every single time. One thing is certain though - when object is hidden than there is no crush due to the rendering. I can attach the bigger file if needed but I narrowed down the crushing to this object hoping that mesh error triggers rendering too). I am attaching the mesh in question for now.

Best regards,
Marko

Hello Marko, can you please share the original mesh alone?

Ive tried exporting this one to obj and after reimporting works well.

Mayube is the original file the problem.

Can confirm crash, This triggered an assert somewhere from drawing code. This mesh seems to have invalid geometry which seems to be root of the bug, as D.meshes['Mesh.001'].validate() fixes the issue.

Can you provide steps to create such broken mesh?
