Frequent editor crash, macOS Catalina, Unity 2019.4.4

Unity Engine
1

I am having an issue with frequent editor crashes on macOS. The crash seems to happen anytime I click on another application outside of Unity (such as Visual Studio or Perforce). As soon as I do, the editor will immediately crash. I am not really sure what may be causing this or how to track down a solution. Here’s is the crash stack trace.

Since 2019.4 is already LTS, you might want to just try upgrading to latest. We’re using 2019.4.8, which was latest when we moved to LTS, and almost the entire team is on MacBookPros running Catalina, and we have no issues there. If you can update, do it.

ALSO: BACK YOUR PROJECT UP FIRST if you are not using source control. You ARE using source control, right??

Other things to try include updating all your packages, maybe reimporting all, that sorta thing.
