Issue: Cubase window jumps to desktop

Hi!

Since update 10.5 I have been having problems with cubase window jumping to desktop screen.
It happens when I close a window inside Cubase. For example when I open a Studio Setup and change the buffer size. Then close the Studio Setup window and voilaa I am not back in Cubase arranger view but instead in my windows 10 desktop or any other window in windows 10. It seems Cubase does not know what was the original window I came from.

All best,

Allan

Same here. But not on all projects. It must be a plugin issue probably.
