Skins wont work at all

On previous versions (1.18.20 for example) skins work fine and so does marketplace, but on 1.18.31. Skins wont load, marketplace wont open, and when I go into a world or realm, the marketplace tells me to restart my game. I've already tried to restart, uninstall my game, connect via ethernet, log out and log in, no matter what I do its the same error.
