Dear XiuFen Ho
I understand how disruptive it is to lose access to your remote desktop, especially when your work depends on it. Based on your description, the issue may be related to authentication or session persistence, particularly if there were recent updates or changes to your network or credentials.
I recommend checking whether any group policies or credential settings have changed on the host machine. If you're seeing an error code like 0x80080005, it may indicate a problem with COM security or remote authentication. Restarting the Remote Desktop Services and verifying that the remote computer is reachable and properly licensed can also help.
If the issue persists, please share a screenshot of the error message or any recent changes to your environment so I can assist further. I appreciate your patience and collaboration. Please click “Accept the answer” to support me. Thank you very much.
