Visual Studio 2019 keeps asking to re-enter credentials for Azure DevOps

I am using the below version of Visual Studio, and I have logged in with my Azure DevOps Credentials. However, again and again, Visual Studio says "We need to refresh the credentials for this account. Re-enter your credentials". Please refer to the screenshot for reference. I have tried removing the account and adding it again. It stays there for some time and then it is asking again. Any suggestions on how to fix this would be very helpful.

Microsoft Visual Studio Community 2019 (2)
Version 16.10.2

Visual Studio 2019 Account Settings

Try this:

in order to reduce the reauthentication, you can try to enable “System web browser” under Tools > Options > Environment > Accounts > Add and reauthenticate accounts using: dropdown. Then, sign in your accounts again.
