Hi,
Please try the following methods:
- Please try to do a clean-boot of the file server, check if the issue still exists in clean mode.
- Please try to uninstall the anti-virus application completely, then restart the System, check if it could work.
- If after uninstalling the anti-virus application, the issue still exists, pleae open CMD, then run sfc /scannow to check if there's any corrupted or missing system files.
- If the above still not work, it's recommended to do in-place upgrade and keep personal files to repair the system.
- If still not work, it's recommended to open a case with MS to do further troubleshooting. Below is the link to open a case with MS:
