Hi,
Thanks for your posting but it seemed that you need capture some traces like procomon to verify what was going on when failed to run wmic command
Sometimes, there will be something wrong with the specific dll which varies.
You can also test by creating a new account and by clean boot to check if the issue is related to third party application.
