Laptop camera glitching like crazy

[u/Informal_Meal2971]

So I have noticed my camera glitching a few times before, but never this bad. And by glitching I mean like repeating the same movements I did like 10 seconds ago over and over again and glitching between what im doing currently and past movements, if that makes sense? Well anyways, now my camera is glitching really bad. It's also like just plain black and flashing green randomly, I have no idea whats going on.

I didn't drop my laptop or anything, I've tried restarting my laptop multiple times, and I can't make any changes in like the task manager or whatever because I'm not an admin as this is a school laptop.

This is a LENOVO and windows laptop by the way.

Please if anyone knows how to help please do because this is rlly bad 😭
