I am using photoshop cc 2018 for mac. I have a VPN though which i connect to a server located in a different country. As soon as i access the server and start downloading/copying any file from the server, photoshop gets hanged completely. Even if I force quit the app and try to reopen it, it won't. It just gets hanged and freezes. It comes back to normal once the download is complete or we disconnect the VPN.
