I was playing Minecraft Java Edition 1.16.5 and one time I came back to find that my character wouldn't turn anymore (I'll often press esc and then do something for a while). I checked my wireless mouse and it still worked, and I checked my trackpad and it still worked, but none of them would make me turn in Minecraft. I could still move, left click, right click, scroll through my hotbar, etc. but I couldn't turn at all. I tried switching between version 1.16.5 and 1.16.4, I tried reseting all my keys, I tried fiddling with the mouse settings, I even tried redownloading Minecraft (I'm not sure if I did it correctly) and it still wasn't fixed!

What should I do?
