thank you very much for your KB-Post. The next time, when the sensor shows this error, can you please use our WMI Tester and scan against this particular target with the following query:

SELECT * FROM Win32_PerfRawData_PerfProc_Thread

and take a look at the result you get? Do you get the same error as in PRTG?

Please also see our extensive WMI Troubleshooting Guide.

best regards.
