Issue with skin weights on character model after Unity version upgrade?

Hi all,

Has anyone ever seen the weights of a character model change after upgrading from one Unity Version to another? I have experienced this recently. I have tears and rips in my characters’ uniforms which did not exist when I was using Unity 2021. Now that my game is using Unity 2022, there are tears and the character body is showing through. Any thoughts about that would be greatly appreciated.
