Blender Version
Broken: version: 3.0.0 Alpha, branch: master, commit date: 2021-04-19 20:49, hash: rB795f024558b8
Worked: (newest version of Blender that worked as expected) It's an experimental file to use in 2.93 and 3.0, but when opening the file in 2.92, I've noticed that undoing the first sculpt mark seems broken.
Short description of error
As the title says, hitting 'Save' (command-s) sometimes crashes blender 2.93 and 3.0 while sculpting a particular object. In addition, the file is occasionally corrupted so that it can no longer be opened, but when I change the backup file from .blend1 to .blend, this version reliably opens but obviously without the last session which crashed. Similarly, after a render/save image, closing the pop up render window sometimes crashes blender.
Exact steps for others to reproduce the error
There seems to be no recognisable pattern so far. More often than not the file saves without issue, but the crashes are pretty frequent compared to previous versions of Blender running on operating systems earlier than Mac os Big Sur.
