Strange, works fine for me on Windows 10 64 bits here.

Same here, no issues on Blender 2.83.0 with Linux.

Seeing as it also occurred in 2.82a for @50p suggests it's a issue with their hardware or the file.

@50p are you able to:

  1. Upload the .blend file.
  2. Upload crash information. This can be done by navigating to the Blender installation folder, run blender_debug_log.cmd, do what you need to get Blender to crash. Once it's crashed, a file explorer should open with two files, upload both of them to here.

I can reproduce the crash with the file provided. Will investigate further.

Upon further investigation, it has something to do with the bevel modifier, however I'm still having trouble reproducing the issue with a new file/object. Will continue the investigation.

I can confirm. But I still don't know exactly what causes the problem.
It seems to be related to linked mesh, Modifiers and UV.

The mesh itself seems to be the issue. If you run with --debug blender will complain about Invalid clnors in this fan!. I'm not sure if this is a DRW bug or a Bmesh one.

  • The crash also happens if you try to add a primitive mesh o the existing mesh (in edit mode > Shift + A > Add Cube).
  • Using another modifier (like subdiv) also crash.
  • Removing modifiers from BOTH instances fixes the issue.

In the middle of looking into this, it seems there is a mix-up between the meshes, as the edit-meshes modifier result has UV's and the other object which isn't using the edit-mesh doesn't have UV's. Need to look into this further.

Uploaded a simplified test file.

I have been testing https://developer.blender.org/P1596 and it solves the issue. I think it is good to be added to 2.90 (and 2.83)
