Can't look around

I was playing on the latest snapshot as of March 6th, 2021, when suddenly I stopped being able to look around, for a second I thought my wireless mouse had died, but it was still glowing. I thought maybe it was a problem with the snapshot, so I logged into the latest release and I still couldn't look around. I restarted my computer, still nothing. I would really like this bug to be fixed soon as I am currently unable to play Minecraft.
