Fusion Studio crash - latest version

I'm getting this warning pop-up intermittently while working (attached screengrab). It was doing it with the BETA version and now is doing it with the very latest release. The popup window cannot be closed as another one immediately pops up making Fusion unusable and has to be shut down in task manager.
Has anyone else come across anything like this?
It seems to happen randomly.

I also have the same experience. But I can't explain the reproduction.
