Before applying the fixes below, it’s important to understand that this error is often related to access permissions or security restrictions.

1. Restart Your PC

Temporary system glitches can sometimes cause access-related errors.

1. Click on the Start menu and select the Power icon.
2. Choose Restart.
3. After rebooting, try accessing the file again.

This simple step refreshes system processes and may resolve minor issues.
