The following symptoms are exactly the same as the public information, and I cannot add an account.

The registry mentioned in the workaround did not exist.
The environment that is occurring is the Windows 10 21H1 multi-session OS used by Azure Virtual Desktop.
Onedrive is installed on a machine-by-machine basis.
Does anyone know a workaround or cause?
Thank you.
