Mouse and keyboard fix after Ventura update?

I have a 2012 Mac Pro (not Macbook, the big metal tower). It was running Monterey fine, but after some other issues I decided to try updating to Ventura. Now, my USB mouse and keyboard won't work. I've tried several different ones of both and don't have any luck.

I can boot into recovery mode, but it just sits there flashing that it's waiting for a mouse and keyboard to connect.

Is there a fix for this, or a way to roll back to Monterey? I don't have access to another Mac, just a laptop running Windows 11.
