I was finished building my creation in the new minecraft 1.17.0.52 beta. and before i exit, my custom 64×64 skin is saved in character creator. Then i launched minecraft again because i import some add-ons in my minecraft world and i saw that my custom skin has changed to Steve 2.0

I was really confused about it because my previous minecraft version is 1.16.230.52. and the custom skins is not buggy that much.

This is my first bug report with my account. Fix it pls.
