Thanks for the Answer

I've updated everything also optional updates.

I downloaded the app again an reinstalled it with the provided link of the support.

It has been repaired several times.

Sorry to hear it. Have you checked to make sure there are no pending updates to the PC or the app itself? If so and you're still having trouble you may need to try a repair or fresh install of the Windows program

I followed your instructions. Login from the app is still not working. From the website, the reply is “We can’t sign you in. JavaScript is required to sign in. Your browser either does not support JavaScript or it is being blocked.” The same thing happens on Xbox.com.
