WYSE keeps getting disconnected? AVD Configuring Session Host

Hello,

-I currently have a newly upgraded 5470 AiO on the latest version of ThinOS 9.

-The thin client device is remote & it's set up to direct RDP into a Windows 10 VM.

-For the most part, everything is working how it should, but every now & then I'm met with this displayed on the screen:

-After exiting that AVD prompt, I'll just click the VDI Menu & double click the direct RDP session to get back in.

-My question/concern is: what is causing this 'AVD Configuring session host' prompt' to appear every now & then & how can I stop it?

-Because this thin client is remote, other people will be using it & I don't want them to be dealing with this prompt often.

System Version  ThinOS 9.5.3102

Microsoft AVD  2.6.2384

Broker Type  None because using Direct RDP Session  with the password set in WMS.

-Any help will greatly be appreciated & I can provide more info/details if need be.
