Unable to start Remote Desktop Service Usermode Port redirector in Windows 10

I have two Windows 10 Pro (Version 21H1) with same GPO applied. The Remote desktop service usermode port redirector service on A can be started. But it is stopped immediately after started on B. There is a message popped "The Remote Desktop Services UserMode Port Redirector service on XXX started and then stopped. Some services stop automatically if they are not in use by other services or programs." There is no event message found in event viewer about the issue. I cannot use RDP to connect the computer without running the service. Could anyone advise how to troubleshoot the issue?

  1. Present.

  2. The 2 dependent services are running.

  3. Did clean boot as recommended but the problem still existed.

  4. Computer A and B have same Endpoint protection software installed with same policy. So it should not be a cause of problem.

  5. Tried but still failed to start the service.

Any other suggestion?
