I have a possible solution. When I upgraded from Win7 to Win10 and even sometimes upgrading from 1909 to 2004 and now to 21H1 I had to do this. Its weird but it worked. After you you start your computer up yes you get the usual loading screen then mine got to the logon screen and right after that my screen would go Black and i had no cursor nothing..I found this crazy fix on some site. Once your screen goes black, press the WIN key + P at the same time quickly and release immediately, then tap arrow up twice, arrow down twice and arrow left Once, then hit enter and your screen should come back on, try a few times doing that and possibly hit the Esc button after Enter you should get your screen and cursor back and it should boot fully to your desktop, then restart your computer again and you shouldnt have any issues after that. This worked for me but maybe you have a different problem, just thought I would see if it would work for you.

Thanks for sharing this.

Would be interesting to know of this fixes the issue for anyone. I've seen a crazy amount of people reporting black/blank screens recently on reddit.
