I sometimes copy files to network shared folders on a Windows 10 host. The action often crashes the Windows 10 explorer, and you would observe that the Windows 10 explorer is terminated and restarted when this happens.
A solution that has helped me was from this discussion. That is, check the "Always show icons, never thumbnails" from the "Folder View". As the following screen captures shows, to access the Folder View, you need to choose "View" from the Folder window, click "Option" from the Ribbon, and choose "Change folder and search options". On the "Folder and Search Options" popup window, select the "View" tab, and from the Fold View, check "Always show icons, never thumbnails", and click the "OK" button to confirm.
