Skin Loading Issue

Whenever I import my skin, then leave the game, I come back and my skin is gone and I have a Steve skin or Alex skin. Every time I open Minecraft, I have to import my skin once again. This did not start happening as soon as 1.16.210 was released, it started happening days after. It is really annoying to have a skin that has to be imported every single time I open the game. It is not just my skin. I tried with other skin files, and I still have the same problem.
