Hello,
This issue sounds like a user profile corruption on the RDS server.
You might need to 1) check or 2) delete that profile by removing it from the registry:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\Current\Version\ProfileList.
Double-click ProfileImagePath. Ensure the correct path to the user account. If the user folder no longer exists, delete the registry key and reboot.
If the profile has .bat extension, then rename the profile by deleting .bak only.
