Github Desktop - cannot push - error about unc paths but not using them

I have high hopes for github desktop - it has
all I need. But we’re not quite there yet.
I can clone the remote repo but cannot push anything back.

My Simple steps:
-create empty directory called valupay2
-use github desktop to clone our remote GITLAB repository
remote: ///devscm01.vtech.com/valupay/valupay2
local path: X:\bd\valupay2

(Yes, the “X” is a mapped drive)

Commit a changed file and then…
At this point I can fetch, but any sort of push gives this error:

‘\florida4\c$\bd\valupay2’
CMD.EXE was started with the above path as the current directory.
UNC paths are not supported. Defaulting to Windows directory.

Ah, another roadblock - maybe I can get some help on this one.
thanks.

To get this message board to accept this I had to alter
the // instances to ///

There’s a pretty clear error message. Depending on the repository configuration you’ll either have to push to another, non-protected branch, or create your own fork of the repository and push to there.
