i can't sign in to xbox (beta) on win10

can you explain your conversation in english please

Tente desistalar e instalar novamente o app , mas reinicie o pc antes de abrir o app.

I suggest you report this as a bug, as it is still in a beta stage. Look out for new updates for it and keep an eye on the patch notes!

i tried every method but it didn't work

Hi SuphanatKhamchuen,

This definitely doesn't look right! Have you tried closing the application down and killing its processes from Task Manager and then retrying?

If that fails, it might be worth uninstalling and reinstalling the software.

Hope this helps, anything else then do let us know!
