So, yesterday my system screen went totally black, even though it’s usually blue. I ran a system update and now the screen is just... gone. Completely vanished. Tried to get it back, but no luck so far.

I tried refreshing it, same way I've always done it before.

I've tried every single combination you can think of—the green stuff in the photo—to bring it back, but nothing works. It's just stuck.
Right when it starts the refresh process, it hits this part (image 3) and then just throws an error at me.

Anyone know what's going on here? System Restore isn't going to help because the screen was already black before the update. If I roll it back, I'll just end up right back where I started with that black screen.
Is there some other way to fix this settings mess?
Everything else on the PC is running fine, everything works perfectly, it's just this one weird screen issue driving me crazy.
