Sourcetree silently crashes on launch (log included)

[Nathanieljla]

Sourcetree suddenly won't open for me.  The splashscreen appears twice then nothing.  I  decided to uninstall, wipe the local %appdata% folders and reinstall 3.4.10, but it still fails (invalid class), so I downloaded 3.4.11; it also has the invalid class exception.  Here's the log:

I'm on windows 10 22H2 (I was on 21H2 yesterday, but I just updated to see if that might help.)
