Lightroom classic hungs up all the time
System: Windows 10 21H2 Build 19044.1645
Lightroom Classics 11.3
Since the last Update, I performed yesterday I got this new very annoying behavior:
Occassionally after doing some changes to a picture, the busy animation in the bottom right is circeling around forevor and never ends with that:

When I click on an other image it doesn't load.
The only way to fix it is to close LR and start again.
I already tried to deinstall and install it again, but this didnt solve the problem.
What can I do?
