I am currently using Windows 10 version 1903, and I have noticed that when I access the Task Manager, the tabs for Processes and Users appear to be empty. Despite attempting to resolve the issue by restarting my computer, I have found that although the tabs initially display the correct information, they eventually become empty again.

Furthermore, if I try to reboot my system after encountering this problem, a message stating “Someone else is still using this pc” appears. In an attempt to identify the user who may be connected, I have used the commands qusers and qwinsta, but I receive an error message indicating “Access denied” with error code 5.
