Minecraft login keeps crashing?

Well, I got Minecraft on my phone a year ago. There went the registration and something. Now I have a new email address and had to buy a new Minecraft. I wanted to log in as usual, but suddenly it crashed. No matter how often I try, it doesn't work. I also restarted my cell phone and tried everything but it just doesn't work. (I've already tried it with Blocklauncher, but the problem is exactly the same. It also crashes. This app only works when I've uninstalled Minecraft) It's still the same phone. What can I do against it? Does somebody has any idea?

I've read that several times now, it seems to be a mistake on the part of Minecraft / Microsoft itself.

You can't do anything for the time being - many have the bug (already reported): https://bugs.mojang.com/...CPE-102943

You'd have to do without it first.
