Minecraft PE crashes after I downloaded an add-on and won't let me sign into Microsoft account

I downloaded an app which let me get texture packs and add-ons for free. I downloaded an add-on and it crashed.

I went back into the app on my Huawei Media Pad T5 and I got signed our if my Microsoft account. I tried signing back in and as soon as it said "Signing into Xbox your Microsoft account", it crashed.

I tried it again, it still continues to crash. I then uninstalled the Minecraft PE app and reinstalled it again and cleared cache and data and the com. mojang files, it still would crash.

Please could you fix this bug/issue so I can play Minecraft again on my tablet?

Also, I can sign in to my Microsoft account on another device on the Minecraft PE app.

 

Thank you for your time
