Problems after WIndows 10 update

After the latest Windows 10 update all my drives disappeard, and now when I try to connect to FTP I’m getting this message

I’m using this credentials for my phone and tablet without any problem

It seems that you need to remove two back slashes in front of the IP address

I am having the same issue after an upgrade.
Mine is a permission error. Please let me know what happens when you remove the back slashes.
