Deleted Microsoft Remote Display Adapter

Question

We have a purpose built PC - Windows 10 Pro with an ASUS RTX3090 GPU that we have had endless RemoteDesktop sessions with.
In the process of diagnosing issues with it the Microsoft Remote Display Adapter got deactivated ( I’m actually assuming deleted since it disappeared ).

We have successfully re-installed it.
However, there is a yellow "caution" icon attached to the adapter, in the Device Manager tree.
I have run every update available at the system level down to the individual adapter in Device Manager. 
However it never gets activated.
The status of the adapter says:
“This device is not working properly because Windows cannot load the drivers required for this device. Code 31
The ALPC message requested is no longer available.”
The driver version of the adapter is 10.0.19041.6.

In the Driver File Details info pane, Three Drivers are listed with the first and last being signed & the 2nd/middle one not signed(Rdpldd.dll).
C:\WINDOWS\System32\drivers\IndirectKmd.sys. --File version 10.0.19041.1
C:\WINDOWS\System32\DRIVERS\UMDF\Rdpldd.dll. --File version 10.0.19041.6
C:\WINDOWS\System32\drivers\WUDFRd.sys. --File version 10.0.19041.1

We can make the initial connection into the PC but then we get the following:
“Unable to connect
The graphics display components in the remote session failed to start up.
Error code: 0x11”



Anyone have any idea how to get the Microsoft Remote Display Adapter to play nice?

Is it possible to re-install all of the RDP components without having to do a system reinstall?

Or can I use the NVIDIA adapter for RDP sessions? I’ve seen 2-3 instances of this being discussed but not too much info really.
