Hello there,
Can you share the exact error message or Event ID you are getting on the RD client device?
Have you made any recent updates that you are aware of on this device? If so try uninstalling them and check if this sorts out the issue
If you don't see the remote resources you're expecting to see in the app, check the account you're using. If you've already signed in with a different account than the one you want to use for Azure Virtual Desktop, you should first sign out, then sign in again with the correct account. If you're using the Remote Desktop Web client, you can use an InPrivate browser window to try a different account.

Hope this resolves your Query !!
