I get a black window for around a second, and then it crashes.

Thankfully I get a mac crash report dialog shortly after! Full contents are here: https://pastebin.com/zzypY0g7

If I'm reading this right, you're on the Catalina update for Mac (ver 10.15), which I only just learned had a compatibility issue with the engine today while I was hunting down news about the new engine they're coming out with.

I'm on Catalina, yeah.  It breaks a fair number of things, for both good and bad.

Thanks!
