Incompatibility with remote credential guard/restricted admin

[conatsera]

Environment

Windows build number: 10.0.22616.0
Your Distribution version: Ubuntu 20.04.4 LTS
Your WSLg version: 1.0.33

Steps to reproduce

1. Have remote credential guard required by group policy.
   Software\Policies\Microsoft\Windows\CredentialsDelegation\RestrictedRemoteAdministration=1
Software\Policies\Microsoft\Windows\CredentialsDelegation\RestrictedRemoteAdministrationType=2
   Administrative Templates->System->Credentials Delegation->Restrict delegation of credentials to remote computer = Require Remote Credential Guard

2. Launch WSL

WSL logs:

• versions.txt:

WSLg ( x86_64 ): 1.0.33+Branch.main.Sha.d57addbe6309d0a453123c91e6117fc21871496c

Expected behavior

For WSLg to not need user credentials to be delegated to it and to launch with this policy set.

Actual behavior

The RDP client gets stuck in a reconnect loop until wsl --shutdown.
In Windows logs TerminalServices-ClientActiveXCore/Microsoft-Windows-TerminalServices-RDPClient/Operational, event ID 1033 repeatedly reports "Component name:OnDisconnected, :: SL::OnDisconnected, Error code:0xE09". I found the text for 0xE09 to be "The remote PC doesn't support Restricted Administration mode."
