System Information
Operating system: MacOS 10.15.6
Graphics card: AMD Radeon Pro 5500M 8 GB + Intel UHD Graphics 630 1536 MB

Blender Version
Broken: 2.83, 2.90, 2.91
Worked: ---

My file "Verenigingstraat" crashed suddenly Verenigingstraat.blend, and now it won't open anymore. All my other files still open normally.

Exact steps for others to reproduce the error
I was working in Edit mode on something architectural and I was only using the Extrude command, combining with shift and control. The usual stuff.
The file crashed so suddenly that I don't know what triggered it.

I've tried opening the same file in 2.83, 2.90 and 2.91. It won't open anymore.

This is the log file I got when it quitted:

P1879

I can confirm that the file will crash. Tested with Blender 2.92.0, Commit date: 2021-01-11 06:58, Hash 64929398fb.

This is similar to e.g. #79793 (Blender crashing on Mac OS Catalina when changing scenes + crashing upon startup when opening certain .blend files)

So yes, we have a couple of corrupted meshes.

To recover those "bad" files, what I usually do is:

from the bad file, append the scene(s) into a fresh empty file [this way you dont have the bad scene active and dont get crashes]
then repair/validate all meshes using the following in the Python console:

[(me.name, me.validate(verbose=True)) for me in bpy.data.meshes]

This way, you can often get most of the stuff back:
Verenigingstraat_repair.blend

But regarding the corruption and bugreports: we have the following policy:

Thanks for the report. Unfortunately unless there are clear instructions on how to reproduce it from scratch we cannot debug this any further.
Things that may cause mesh corruption: Importers, development versions of Blender, modeling tools.

So afraid we have to close this, but feel free to comment again if this happens again and you can provide reproduction steps
