Hello Kurniawann,
thank you for posting on the Microsoft Community Forums.
The issue you are experiencing could be caused by a number of factors, including a corrupted user profile, a problem with the graphics driver, or a problem with the Windows Explorer process.
To resolve it, you can try the following steps:
- Restart the server and see if the issue persists.
- Try logging in with a different user account to see if the issue is specific to your user profile.
- Update the graphics driver to the latest version.
- Run a system file checker scan to check for any corrupted system files. To do this, open Command Prompt as an administrator and type "sfc /scannow" without the quotes and press Enter.
- If none of the above steps work, you may need to consider performing a repair installation of Windows Server 2019 Standard.
Hope it helps.
Best regards,
Lei
