Adobe DC crashes

[Jack157F]

I'm running Windows 11. Everything was fine until a few weeks ago. (I'm suspicious of one of Microsoft updates.) Now when I start Adobe DC it sits there for a few seconds, then it produces this mysterious blank box (see attached) and crashes. I've tried all the usual tricks, uninstall/reinstall, etc. I tired the Adobe "cleaner". Nothing seems to help.

This is a desperate situation since I can't work on any of the forms while this is going on.

HELP!!

Does anyone have any ideas here? Where is Adobe support? This is very serious.
