I know how to Rigging a Blender 3D, but after testing it, it worked well, but the right arm doesn't look like a problem in the armature, but it gets crumpled in a strange direction. And I thought it was the mirror, but it wasn't. I kept looking for a solution, but I couldn't find it. Please help me as soon as possible. Thank you very much. I'll leave a screenshot.
