The same issue is still occurring in 2021. I had tried the sign out/sign in method, I had tried the local app data deletion method. No luck with either.

What worked for me were the following steps.

• Click on your name in the top right corner of Visual Studio and select Account Settings
• Now rather than signing out, look below this to the All Accounts section. On some it will say "We need to refresh the credentials for this account"
• Re-enter your credentials here.

This fixed the issue for me. I hope this helps someone else with this annoying issue.
