Task Manager - Processes & Users Tab empty

I have Windows 10 1903 and it's some time that if I open the Task Manager, the Processes and Users tab are empty.

After trying to reboot the system, I found out that immediately after the reboot, the processes and users are showing correctly, but after a while they stop to show up.

Also, if I reboot the system after the issue showed up, I receive the message "Someone else is still using this pc"

I tried to use the commands qusers and qwinsta to see who is the user connected, but I receive the error Error 5: Access denied.

I've also tried what is suggested here, but to no avail.

I see that you are an italian like me and I also had this exact problem.

In the end I found that the problem was a program needed for the CNS (Tessera Sanitaria), in particular the one called IDProtect (it's only for the ACTALIS type of CNS, see this link for more information).

Remember to close the task manager, shutdown the program and then reopen the task manager to see the changes.
