Can you confirm which Azure service you are using. Is this Azure Virtual Desktop or Microsoft Dev Box?
If Dev Box you can post on their dedicated forum here. The below answer was generated by Microsoft Copilot:

It seems you’re encountering an issue with FSLogix where the user profile fails to attach. Let’s troubleshoot this:

Corrupt Profiles: First, try deleting any corrupt profiles from the registry location: Local_Machine\Software\FsLogix\Profiles. Then navigate to the path of VHDLocations and delete the profiles. Signing back in should create a new profile(https://learn.microsoft.com/en-us/answers/questions/200605/fslogix-error-the-user-profile-failed-to-attach).

Storage Allocation: Ensure that the storage container for FSLogix in Azure has sufficient allocated space. If it exceeds the allocated limit, it can cause issues(https://learn.microsoft.com/en-us/answers/questions/200605/fslogix-error-the-user-profile-failed-to-attach).

Recent Updates: If you’ve recently installed Windows updates, particularly KB5005568 or KB5005625, they might have affected FSLogix. Consider uninstalling these updates or checking for compatibility issues2.

Temporary Profiles: Check for temporary profiles and delete them:

Go to Control Panel → System → Advanced System Properties → Advanced → User Profiles → Settings.

Delete any profiles with Type set as TEMP(https://learn.microsoft.com/en-us/answers/questions/491256/fslogix-error-cannot-get-user-profile-to-attach).

Virtual Disk Access: Reboot the machine during off-hours, log in with an admin account, and delete the user’s VHDX. Then ask the user to log in again to see if the new VHDX attaches successfully(https://learn.microsoft.com/en-us/answers/questions/349366/fslogix-profile-failed-to-open-virtual-disk). Remember to back up critical data before making any changes. If the issue persists, consider reaching out to support for further assistance.
