This points to an error with WMI service. If restart of WMI service or machine restart doesn't help, you need to diagnose and possibly repair WMI repository.

Hello

thanks for your answer, but it seems there is no problem with the repository.

winmgmt /salvagerepository -> WMI repository is consistent
