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?
System Information
Operating system:MocOS Big Sur 11.1 2.4 GHz 8-Core Intel Core i9 64 GB 2667 MHz DDR4
Graphics card: Intel UHD Graphics 630 1536 MB
Blender Version
Broken: Version 2.91.0 (2.91.0 2020-11-25)
Worked: (2.81)
Blender crashes randomly on Mac OS. Sometimes after just sitting idle for several minutes, other times after editing meshes or attempt to render in viewport (Cycles or EEVEE) or render frames or animation.
Very hard to find a definitive pattern when crash occurs.
Seems that when I create files on version 2.83 or 2.91 it works better, but loading files (especially large files) from earlier versions crash very often.
See OS crash log below :

The problem appears to be in the graphics driver since it occurs in
glDrawElementsInstancedBaseVertex
.Unfortunately the crash log does not provide enough information for developers to be able to identify and provide a workarround for this OS.
There are plans to port blender to a different rendering API (Vulkan). Problems like this are expected to be resolved.
This might be a duplicate of #83791 (Blender crash on iMac Pro with Big Sur)
Also noted that crash occurs when MacBook goes to sleep with Blender active and then woken. As soon as the viewport is activated Blender crashes
