Same skeleton , but character skeleton deformation when assign with SK_Mannequin in unreal engine 5

Hello everyone, I have a problem that I need help with. When I assign a new character skeleton to SK_Manequin, the character mesh is deformed in 2 hand positions like this, the other positions are normal. Is there any way to solve this problem? I fixed it following this guide but it didn’t work. https://www.youtube.com/watch?v=xtQDzDcoxcc
