This occurs when you perform the operation on a CSV owner node from a process that doesn’t have administrator privilege. Do one of the following:
  • Perform the operation from a process that has administrator privilege.
  • Perform the operation from a node that doesn’t have CSV ownership.

Microsoft is working on a resolution and will provide an update in an upcoming release.
After installing KB4493509, devices with some Asian language packs installed may receive the error, “0x800f0982 - PSFX_E_MATCHING_COMPONENT_NOT_FOUND.”| This issue is addressed by updates released June 11, 2019 and later. We recommend you install the latest security updates for your device.

Note If reinstalling the language pack does not mitigate the issue, use the In-Place-Upgrade feature. For guidance, see How to do an in-place upgrade on Windows, and Perform an in-place upgrade of Windows Server.
