the same thing happened to me as well.
it looked like whatever was holding the wheel on the left wheel button broke so the wheel itself was at an angle from the spring on the right wheel button pushing it.
the wheel was also spinning freely as compared to the tension that was there when the wheel turned one 'click'.
although I doubt the images below would help, I hope they do.
also if the images disappear at some point it's because I linked them from Discord since for some reason I couldn't upload them directly.
however, except for that, everything thing else seems to work just fine.
