It dies on me too. My call stack looks like this:

The object that causes this is called "Server Rack" and it contains one mesh called "Cube.014". It dies in mesh_render_data_polys_sorted_build. It arrives with a MeshRenderData containing:

extract_type: MR_EXTRACT_BMESH
poly_len: 65616
edge_len: 130784
vert_len: 65896
loop_len: 262080
edge_loose_len: 0
vert_loose_len: 0
tri_len: 130848
mat_len: 10
...

It makes it to the "Sort per material" section then dies on line 226 BM_ITER_MESH_INDEX (f, &iter, mr->bm, BM_FACES_OF_MESH, i) {

It dies in T &operator[](int64_t index) because the value of index is -15672, but expected to be 0 or greater.

Can't see much more. I don't seem to have any other files that get here with mr->extract_type == MR_EXTRACT_BMESH so hard to tell what is wrong. And hard to debug inside this BM_ITER_MESH_INDEX macro.

@Harley Hey, try to bisect this, most likely something from Hans's refactorings on the structure of the mesh

Hi, can confirm the crash. Mesh.validate has detected the invalid data: https://docs.blender.org/api/current/bpy.types.Mesh.html#bpy.types.Mesh.validate
Did you import this file from other software? or Is this file originally created in old blender versions?

ERROR (bke.mesh): C:\Users\blender\git\blender-vdev\blender.git\source\blender\blenkernel\intern\mesh_validate.cc:574 BKE_mesh_validate_arrays:         Poly 23 has invalid material (-15672)

This mesh was created in the current version of Blender. I started it about ~2 weeks ago.

@janosdebugs , can you verify whether uploaded file is not crashing?
@mod_moder , I don't think bisect is needed. Crash even happens in 2.93 :)

@janosdebugs , can you share exact steps to reproduce the file from scratch?

@PratikPB2123 tested, it doesn't crash.

@janosdebugs , can you share exact steps to reproduce the file from scratch?

Sadly, I can't. It's been a fairly long process. I removed a bunch of stuff on Linux to isolate the issue to the server rack. I remember starting from a cube, then go the usual way to loop cut, subdivide, and building faces manually. What I also did was join meshes into the same object. Possibly unrelated, but other meshes have lots of materials on them (~30-40).

Unfortunately unless there are clear instructions on how to reproduce it from scratch we cannot debug this any further.
Sorry but I have to close this report as per the triaging policy. Feel free to comment or reopen the report if you have additional and relevant information to share.
