User Access Issue: Login Redirect Problem with Git Credentials

Hello I need some help with a user access issue. One of our users attempted to log in using their Git account instead of their regular credentials. Now they're unable to access our company workspace and are consistently redirected to the subscription page after login. The issue seems to be that the key in the URL isn't redirecting them to the correct workspace after authentication. When they try to force our workspace key in the URL, they receive a 404 error. Thanks!
