When recomposing a Horizon View Persistent VDI to use a new snapshot I get this error: "View Composer agent initialization state error (21): Failed to mount system disposeable disk. Please check the parent VM is an existing disk is using the same drive letter. (Waited 0 seconds)"
The VDI pool is configured to use letter Y for disposeable disk.
If I do I a RDP to that VDI logged in are the user owning that VDI I see letters C,D,E,F and G in use and E is SystemDisposeable Disk, F is PersistentDataDisk and G is InternalDisk.
If I do the same as the local admin I see the same.
If I log on to the golden image VM I see only a C drive.
OS is Windows 2019 Build 20H2. All Windows updates applied as per 30/6 2021
VMware Tools is 11.3.0
Horizon Agent is 7.12.0
All involved Horizon Servers are 7.12.0
