Macbook pro 16'' / 2,4 GHz Intel Core i9 8 core / 32 GB 2667 MHz DDR4 / MD Radeon Pro 5500M 8 GB / Intel UHD Graphics 630 1536 MB

Blender 2.90.1 (2.90.1 2020-09-23)

I had two main collections (Model and Scene) with more nested collections inside them, I unchecked the visibility on the layer pannel for the "Mode" collection for can work easier on the mesh.
I was erasing somes faces on a mesh in edit mode (with cycles I think in render view), then I extruded the rest faces and blender crashed.
When I reopened the file everything was good until I tried to make visible the "Model" collection at that point Blender crash.
After the first time that I risked to loose my entire project now I save a backup copy every time I save the main file, but this time I don't know why even mi Backup copy is corrupted, I can't even open it that blender crash, same issue with auto save copies (only a 5 hours earlier auto save worked) and blender automatic backup files (.blend1 ecc.)

I tried also to erase the object form the files but it still crashing, if I try to append the model collection on a new file it still crashing.
So now I'm working on a 5 hours earlier auto save copy and I'm trying to recreate all the new stuffs :(

This looks a lot like #82353 - I haven't checked because the files to download are very large - due to the fact that an invisible/disabled collection is mentioned here.

Since your backup files are also corrupted, that provides more evidence that it wasn't the crash the caused the issue, the bad data was already written to the files beforehand.

This does appear to be the same issue, but as with the other ticket we would need a way to reproduce the issue.
