Restart Windows

Please note that these solutions apply to Windows 10 and 11 and the steps are almost the same.

If the problem may be coming from external devices such as drives or other devices, safely disconnect them and see if the error persists. All versions of Windows generally don't care if you unplug a USB device when needed, but doing it safely will ensure that the data is preserved.
