Hello Collin Anderson,
The issue pertains to a loss of administrative access to the Azure DevOps organization after it was connected to Microsoft Entra ID, leaving no user with sufficient permissions to manage the organization.
To resolve this, guided you to create a new internal user account and involved Azure DevOps engineering team to add the newly created user to the Project Collection Administrators (PCA) group from the backend. After the backend changes were completed, the new user was able to access the Azure DevOps organization successfully, restoring administrative access.
