Very slow "UNDO"

Cmd-z Mac Ball of Death

Probably just a easy bug fix but I just recently upgraded to Rhino 7 for Mac. I’m running the latest version of Rhino on Mac OS Big Sur. Every once in a while when I cmd-z to undo I will get the spinning beach ball and have to eventually force quit Rhino. Seems like it happens randomly. The project I’ve been working on is very simple and small so I’m not sure why my computer is struggling. If possible I can attach a crash log if that helps resolve the issue.
