My hypothesis is that the nether coat an item that was free isn't anymore, and because of that my skin which has that item on cant be loaded. but its annoying because now anytime I enter the main menu it tries to load that skin and says "skin 2 failed to load"

just checked back now two of my skins are doing that and I have a new hypothesis, either this is the same this a free item that I was wearing isn't anymore there for making the skin broken and unload-able. OR because I play on Xbox and windows 10 maybe it bugs itself when transiting the skins do transfer from game to game I do not know.
