I am not sure if this will work but you could have a try that use another process monitor to capture traces and analyze together with the Windows performance recorder by timestamp, since procmon will help to record detailed process or services.
Moreover, for the general problems related to remote desktop service, it is always suggested to check the event logs as well.
Event log checking:
TerminalServices-RemoteConnectionManager and TerminalServices-LocalSessionManager logs to view information about connections.
Step 1: Press Windows+R to open the Run dialog, enter eventvwr (or eventvwr.msc) and hit OK.
Step 2: Navigate to Event Viewer\ Applications and Services Logs\ Microsoft\ Windows\ TerminalServices-*
Hope this helps and please help to accept as Answer if the response is useful.
