Azure Virtual Desktop - Black Screens on logins - What we've tried so far

To address the black screen issue in Azure Virtual Desktop, my stable approach for now is to roll back to the previous update, specifically KB5039211, as the next update has not yet been released. Additionally, it is advisable to test any Known Issue Rollback (KIR) on a test host pool before deploying it in a production environment to avoid potential issues with other applications. For short-term stability, consider rebuilding environments from a Golden Image that does not include the problematic patch and disabling the Windows Update service temporarily and create a rings for updates. Always ensure to test all updates and patches in a controlled environment before rolling them out broadly.
