I have a custom built dual boot system(Linux Ubuntu 20.04 and Windows 10). When trying to troubleshoot a device problem in Windows 10, the Device Manager screen keep blinking as if it is restarting and will not let me select the device I'm having problems with. (Very fast blinking). What could be causing this?

4. Press Windows key + R key together. When the Run dialog appears, type devmgmt.msc and press RETURN/ENTER.
5. When the Device Manager window starts misbehaving, swap to the ProcMon dialog and press CTRL+E to resume event logging. After a few seconds, press CTRL+E to stop event logging. Problems with Device Manager should show in the Results column, probably as FAILURE.
Report back with the results.
