Need help with animation bug, dont know if this is the right category

I have no idea where to put this but there is a major bug with the animations in my game, everything was working perfectly yesterday but now when I change the width and depth to my character to 0.9 it suddenly glitches and the animations looks all weird, this was not a problem before and I could change the body depth and width without any problem.

This is the difference, but you can see the arms are like all weird.

you’re possibly playing two animations or using a different rig with different motor6d positions to animate or play on. There might be more possible reasons but those are the ones I can come up with
