Macbook Pro freezes for 15 seconds when using hot corners

I have set a Hot Corner to show Application Windows and switch between them but almost every time I use it the windows get frozen in their position and can't be selected (blue border around the selected one) to use.

I can still click things and write text in the reduced size windows but need to wait for 10-15 seconds before it can be selected and to become full size again.

Any idea where this problem could come from?

I have a MacBook Pro 13" 2016 model running Big Sur 11.3.

3.3 GHz Dual-Core i7, 16 GB RAM

MacBook Pro 13″, macOS 11.3

So I've had time now to start in safe-mode. But I could not test it as the system was really sluggish and after starting Safari with around 40 windows I've got logged out and ended up at the user login window. This happened twice before I restarted in normal mode.

This might be a different issue but it doesn't make sense to me that in safe-mode the system can't handle things it can easily in regular mode. Maybe I have to reinstall macOS.
