I have these issues too, it's incredibly annoying as I'm set to the Alex default skin.
I've tried restarting, reinstalling, clearing cache, swapping to mobile and back, so far nothing. I can access servers just fine, yet I am unable to access the marketplace or the skin editor. Curiously, the marketplace loses the error notice on the home page after loading into a world and back out, but clicking on it does nothing, and the marketplace in-world remains errored out.
