First Windows 10 hang up, blue spinning ring entire PC locked, randomly browsing MediaBay files

My second issue so far with Windows 10 and Cubase 10.5. (Coming from Windows 7)

Was browsing my MediaBay samples and for some time, everything was fine, just using my keyboard arrow keys to move down sample to sample. Then all of a sudden I get a random blue spinning wheel and the entire program and PC is locked up… for a good 20 or 30 seconds… Was about to ctrl+alt+delete or force a power shutdown, but then it got unstuck.

My first problem was: Cubase 10.5 graphics acting glitchy on fresh Windows 10 install - Cubase - Steinberg Forums

None of these problems on Windows 7 and Cubase 10.5, so I’m glad I’m reformatting my Windows 7 machine one final time, and will probably be sticking to it for another year or two… Even if I can’t hack Cubase 11 onto it.
