It’s hard to tell solve your problem since we don’t know what objects are in your scene. Try to check if there is collision overlap with each other. One best way to solve is to make a new scene and drag all your models back to the scene again. Again, we don’t know the detail of things that are in your scene , so we can’t know exactly what the problem is!n’t know exactly what the problem is!
