System Information
Operating system: Windows-10-10.0.22621-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 4090/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 528.24

Blender Version
Broken: version: 3.5.0 Alpha, branch: master, commit date: 2023-02-06 01:50, hash: rB2627635ff3ae

Caused by 6c774feba2

Short description of error
Blender crashes after using Inset Faces (when a UV map is present)

Exact steps for others to reproduce the error
1 - create poly sphere
2 - select several polygons
3 - use Inset Faces (with the settings as in the screenshot)
Sometimes after this operation Blender crashes

in a debug build with ASAN, this will reliably give

SUMMARY: AddressSanitizer: heap-buffer-overflow /blender/source/blender/bmesh/intern/bmesh_mesh_convert.cc:1030 in BM_mesh_bm_to_me

Hi, thanks for the report.

Seems as duplicate of #104344

That could be a platform specific issue.
@borschberry , I'm not able to redo the crash locally.
Can you share crash logs?

Please open Blender's installation directory and double click on the blender_debug_gpu.cmd. This will start Blender in debug mode and create log files. Try to reproduce the
error again. Once it crashes or you close Blender manually the Windows Explorer should open and show you up to two files, a debug log and the system information. Add them
to your bug report by clicking on the upload button as shown in the screenshot below or via drag and drop. Please also upload the crash log located in C:\Users\[your username]\AppData\Local\Temp\[project name].crash.txt (or simply type %TEMP% into the path bar of the Windows Explorer).

Could you also try factory reset?: File > Defaults > Load Factory Settings

Hi, managed to trigger the crash in debug build (Still unable to redo crash in release build), confirming.

Crash in BM_mesh_bm_to_me after a few simple face edit operations including bevel #104379

Getting this in debug with any Inset (if there is a UV map present)

SUMMARY: AddressSanitizer: heap-buffer-overflow /blender/source/blender/bmesh/intern/bmesh_mesh_convert.cc:1030 in BM_mesh_bm_to_me

suspicion is 6c774feba2, will check
