Game view screen black and console flooded with errors

Hello, I really hope someone could help me with this, as I am at a loss on what to do.

I had to force close unity at some point because it was not responding. I was in the UIBuilder when it froze. After restarting the computer for good measure, I try to open the project again from Unity Hub, but now it looks like this:


When I move the mouse over the black area, the console prints the errors at an increasing pace.

Anyone that knows what is going on here?
