Minecraft keeps crashing/stopping working when I try to log in with my Xbox account

Recently I tried to play on my friend's realm, but when i tried to join in a message saying that my Microsoft account needs services authentications pop ups, then it returns to the previous screen. I tried to log off my account but it crashed. I tried several times, it just didn't work. Then I uninstalled and reinstalled the app and tried to log in, but it also crashes. Of course I tried several times too. Also tried doing some things, such as:
Putting my phone on airplane mode for like a min and then retry.
Restarting my phone.
Cleaning the app's cache.
Thank you if you know how to help.
