Game not running right, maps suddenly going too "fast" and it's impossible to react? (Fast song settings not enabled)

I'm using an Oculus Quest 2. About a month ago songs were suddenly impossible, in that the blocks would seem to appear only when they were already super close and there would be literally no time to react and hit them. I'm not great at this game but before that I could pretty easily do easy and normal mode songs. Now every single song, no matter the difficulty, has become impossible. I just got a USB-C cable, thinking it was probably some kind of lag due to the fact that I was using AirLink wirelessly. But the problem has persisted and might even be worse. I am also using mods. I made sure that I don't have the "fast song" or "super fast song" settings enabled. Does anyone know what the problem might be? Did I get a shit cable?

Thanks!

Edit: I'm using BeatSaber on Steam, and I have a 3060ti and i7-11700K so I don't think it's a problem with my computers specs. The cable is USB-A to USB-C, and it's plugged into a USB 3.2 gen 1 port on my PC.
