Minecraft PE is crashing upon login.

Same problem on my child's account. It was working fine, then changed her email address, now it crashes every time she tries to log on. Microsoft you made a 5 year old cry, shame! ;-)

I found that there is an issue with Microsoft Account and the Security Auditing Policy on my local machine when authenticating to Xbox Live & Minecraft.

Example:

My MS Account was originally @gmail.com

I changed my primary alias to @outlook.com

This throws a security audit exception when authenticating to Xbox Live with Minecraft.

In short... Xbox tries to verify @outlook.com, OS expects @gmail. Minecraft dies.

Solution:

Move my primary alias back to what Windows 10 was expecting (@gmail). Problem solved.

You can verify this by looking in your Event Viewer after Minecraft Crashes. Then look in the Security Audit logs to see what user name its trying to match up against.

wait what if you changed your primary alias from gmail.com to gmail.com?

thanks for the reply, but it did not help.

In events log this is what I get:

and it seems like it occurs simultaneously with this error:

Ive also been having the same issue, its fine when i load up the game when im not signed into an account but the second i sign in it instantly freezes and i have to manually close minecraft.

For me, you can fix for a little bit by unistalling (which also is being weird and taking too long just to unistall) and then re-installing minecraft. But you have to do it everytime you launch minecraft and its annoying to have to unistall then reinstall
everytime i want to play.

Please help

(Edit): you may need to hard reset as well
