Dell ThinOS 2211 (9.3.3099) RDP Disconnect issue while copy

Hello all,

My organisation has 16 thin client and all at 9.3.3099 firmware 

Now some weird RDP disconnect issue occur

For my case, I can trigger this error simply by just copy(Ctrl-C) for this sample text "\\tsclient\remote-disk-1" [without the double quote] will cause AVD to disconnect

Does anyone face this issue after upgrade? and how you handle this.

Thank you in advance
