Perform SFC or CHKDSK scan

Running an SFC scan can fix the error by repairing corrupted system files related to the proper functioning of ACL. If files are missing, the DISM scan will replace them using the Windows system image file stored in the cache. If both scans do not work, the issue may be related to the hard drive error, which you can fix by running a CHKDSK scan.

Step 1: Type Command Prompt in the Windows search bar → Choose Run as administrator to open with administrative privileges.

Step 2: Enter the command SFC /scannow → Press Enter (Make sure to add a space between SFC and /scannow).

Step 3: When the scan process is complete, Command Prompt will display a scan result message. If any corrupted system files are found, SFC will attempt to repair them.

Change ownership of affected file or folder

Step 1: Right-click on the File or Folder and select Properties.

Step 2: Switch to the Security tab → Click on Advanced.

Step 3: Next to the Owner section, check if your username is listed as the owner of the file or folder. If not, that may be the issue. So, click on the Change link next to it.

Step 4: Select Advanced to open the Select User or Group dialog.

Step 5: Click Find Now to search for available users on your Windows computer.

Step 6: In the search results below, select your Username and click OK.
