90% of all my macOS students have this issue
This is an extreme worst case scenario since we cannot work with 2.91 at all
but that is the one with the new boolean code !

System Information
Various systems iMac - MacBookPro
Catalina and BigSur

Blender Version
Broken: version: 2.91.0, branch: master, commit date: 2020-11-25 08:34, hash: 0f45cab862
Worked: 2.8.x

Short description of error
students work and blender crashes and then makes the file not usable
Cabin Corrupted.blend

cabin Rescured.blend

crash.rtf

Exact steps for others to reproduce the error
students work
Blender crashes
File is corrupted then
Blender crashes when loading the file

Appending all collections into a new file fixes the issue
But interestingly the boolean modifiers are lost

I cannot reproduce it. I can open both files just fine on:

System Information
Operating system: Darwin-18.7.0-x86_64-i386-64bit 64 Bits
Graphics card: AMD Radeon Pro 560X OpenGL Engine ATI Technologies Inc. 4.1 ATI-2.11.22

Blender Version
version: 2.92.0 Alpha, branch: master, commit date: 2020-12-25 22:13, hash: 8491e4ab86

Did you try with latest blander or with the --factory-startup flag ?

Both project files open fine for me as well and validating the meshes shows no corruption either. I've tested this on Linux. That being said, there are known issues with Blender on macOS that can lead to corruption such as #82353.

We would need precise steps that result in a broken file and an example file that demonstrates the problem to investigate this further.

Hi Folks I renamed the wrong file by accident being the corrupt one.
I uploaded the correct non working blend file.
See if it crashes on your side.

Regarding the steps: Students reported how it simply crashed at various different steps and then the file did not open.

So it seems not just a single thing caused the crash and corruption of the file.

I can see that the file results in a crash, but we would still need steps to reproduce the corruption on our system to investigate the problem. If this happens frequently, please try the following and check if this avoids the corruption:

Open the user preferences (Edit > Preferences)
In the Interface tab enable Developer Extras
In the Experimental tab enable Undo Legacy

@ClaasKuhnen Some issues in the Undo system (e.g. #84397) have been identified and fixed in the meantime. Please test if the problem still occurs in the daily builds of Blender 2.92 .

Ah that is very good to know.

@ClaasKuhnen Were you able to test this in the meantime?

I can just confirm that Blender 2.93 Alpha 2021-01-23 21:10, ded9484925 is unable to open this broken file and crashes right away. MacOS Catalina 10.15.2

@isbm That is expected as the file is broken. The question is whether the corruptions still occur in projects created with 2.93.0.

@ClaasKuhnen Where you able to test the newer Blender version and did the situation improve?
