Blender 2.83.0 crashes on macOS Catalina. Blender crashes when attempting to open the blender-file afterwards. #77840

System Information

Operating system: macOS Catalina 10.15.4
Graphics card: Radeon Pro Vega 48 8 GB

Blender Version

Broken: v2.83.0

Short description of error

I've experienced this problem multiple times in Blender 2.83.0. First, Blender crashes. After that, when I try to reopen the project, Blender will crash immediately (the file has some how been corrupted). This has happened multiple times on commercial projects that I work on.

This exact problem happened just now when adding a cylinder to the scene.

Although I love Blender and use it daily in my job as a graphics designer at a music software company, if this continues, I'll be forced to find another 3D Software.

Exact steps for others to reproduce the error

Here is a WeTransfer link that contains two blender projects for which this has happened. They crash on both of my Macs when opening them.

It is possible to attach .blend files to this bug report.

Yes, they're 400 MB total, which is why I used WeTransfer. I'll add them here also then.

Possibly related issue with mac here...I know my specks are basic, but I thought it might be worth mentioning.

System Information
Operating system: OS Mojave 10.14.2
Graphics card: Intel Iris Pro 1536 MB

Blender Version
Broken: 2.83
Worked: 2.82

Short description of error
I downloaded 2.82 for the first time and it was all working very smoothly. I downloaded 2.83 and as soon as I opened blender, the default cube in viewport was laggy. When I opened my blend file with cycles rendering and many added layers, it became unusable. I've reverted back to 2.82 and initial lag is gone.

Exact steps for others to reproduce the error
Based on the default startup.

Also crashes here, crashlog attached.

It happened again today. Blender 2.83.0 crashed while rendering. Afterwards, when I try to open the project again, the file has somehow been corrupted after the crash and Blender crashes when attempting to opening it. I've attached the file here:model_crashing_2.blend

I can confirm the problem. But has this file ever worked before?
I tested it on older versions of blender (2.80, 2.82) but none of them open this file.

If the file is corrupted during save, it would be good to identify what causes this corruption.

Can you check if there are saved backups of this file? it can blend1 or blend2 files with same name. Can you open one of those?

Identifying what caused corruption would be impossible from those files we would need at least stack trace of crash when it happened.
