(PC) We couldn't sign you in to Xbox Live (0x80070520)

Hello,

Any time I try to use an Xbox Game, or sign into the Xbox app with my main profile, I am given the following error,

We couldn't sign you in to Xbox Live (0x80070520)

When I click the link, I get the following: Sorry! No Support articles were found for "0x80070520."

I created another profile, and it connects in ~2 seconds, with no issues whatsoever. My main profile, however, immediately shows the error box as soon as I click sign in, appearing to not take any time to attempt a connection.

I am able to log into my profile on microsoft.com, and I use this profile to log into my PCs, but it simply cannot use Xbox services

:)
