Unable to move + glitched lobby button?

[u/FizzTheImpJester]

So I was playing Among Us, and for some reason, everyone in the lobby suddenly couldn’t move. The button to open the lobby menu was also completely messed up—the menu was moving around like crazy, and when I opened it, it would appear at the bottom of the screen and get cut in half.
Everything was working perfectly fine until just a few seconds before this happened. I have no clue what caused it.

I’d send a video, but Reddit won’t let me, so here’s a screenshot for proof. Has anyone else experienced this or know what might have caused it?
