Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?

Short description of error
I am getting many many crashes in Blender when switching to a different app and then, after a while, switching back. This will often cause Blender to crash right when it tries to come back to the foreground. The crashes don't seem to have any relation to what's otherwise being done inside Blender.
It's possible that this is a Mac-only issue, or even Big Sur only, or even specific to my MacBook Pro model (16-inch, 2019), or it's drivers, but I will leave this here in the hope that perhaps someone can reproduce similar crashes, or simply make sense of the crash reports provided here.
Exact steps for others to reproduce the error
After a while, Switch back to Blender

Checking the first few crash logs, they all seem different. So I smell another tricky one.
Or could this be the same issue as #80203 & #84397, which got fixed with abbc43e4e419? Although looking at the last log, this build seems to be from 3 days after the fix...

Hi, I think I'm getting the same issue. Happens quite frequently and matches the description from the OP.

Hi, this keeps happening to me. If I leave my Mac for a while, when I come back Blender often just instantly crashes. I have included info that I think is relevant but I'm new to bug reporting so if I've done anything wrong can you let me know. The attached file is copied from the macOS crash report window. Thanks.

Isnt this the same as {#70856}?
Will merge this with #70856 (macOS: Blender crashes when I log in/wake the display) now, please comment again if you think this is not the same.
