Random sudden physics jumps in Live2D

After rigging the body, it started jumping like this. Usually, this “jump” happens very rarely and literally lasts for a second, but this time it lagged so badly that I was able to record it.

I tried changing the output to Position X, Angle X, and Body X, and I also changed the Scale, but nothing helped. When I adjust the parameters manually, this never happens.

And the problem isn’t that I’m moving the mouse too far either, because I have exactly the same issue on another model. It happens very rarely on that model, and it even happens in VTube Studio when my face is being tracked.

With this particular model, it usually only happened to the lower part of the body (the Hips parameter, and all the angles are synthesized). But in the video, the entire body jumps, which is the first time that has happened.

I honestly have no idea what to do, and I can’t find anything about this problem. The only advice I found was to reduce the Scale, but that doesn’t help. I'm a complete zero in physics, so I really hope you can help me!
