Note: I was dealing with the #9 error and also crashing when I was logged in since the Bee update. Finally yesterday, I toggled a setting for automatic updates from the market in my profile and then I was able to login and access realms and the markets as usual. I am playing on android. Hope that helps someone.

I reported the same issue here: https://bugs.mojang.com/browse/MCPE-63071 (just a note they marked my ticket as private as we were sharing some account info)

If you can manage to logout, you can still get in an play your saved worlds while they work this out. You won't however, be able to access your online features.
