Unable to access target folder

After the latest update, I get an error message when trying to copy a file from a directory on my computer to another computer on my network via a mapped drive. The file copies fine when I open the same mapped drive location via the Network folder path. Before the last update, I experienced no issues with copying files via mapped drives.

File won’t copy:

G:.Apps\Teracopy

File will copy:

\\MEDIASERVER\geek\.Apps\Teracopy
