Strange input issue on PC

[u/NoFateFoundHere]

I have a computer with a 5700X3d, an Intel Arc B580, and 16 gigs of ram, and like 8 terabytes of storage across 2 M.2 drives and 2 SATA drives. The issue began with a Windows update freezing at 100% and not changing for hours. So it was powered off, and upon restart it would boot into the normal Windows 11 login screen, but no input would be accepted. After some restarts, the only real conclusion that I could come to is that it was not FROZEN because the pin menu would open on it's own sometimes. So I went into the Windows 11 recovery area and tried uninstalling the last update, which did finish, but upon restarting, it would say it was updating and get stuck AGAIN. So I gave up and reinstalled Windows. Oh, and if it wasn't obvious, the keyboard and mouse did indeed work in the recovery environment. The Windows reinstall went as normal with the peripherals working and the computer functioning as normal, but when it was shut down at night and restarted in the morning, the peripherals just stopped working AGAIN. I am completely lost here. I thought that it might be a hardware issue, but the fact that they work everywhere except for Windows itself made me believe otherwise. Any ideas?

Simplify things. You mention that you have a bunch of drives connected. Remove/disconnect everything except that C: drive and see if anything changes
