Yes that did it! Thanks @mjpenny !
For any following after here with long paths to Paratext, final form of the solution is to make a symbolic link to your Paratext folder and point the shortcut to it.
Open Terminal.
Paste this command:
mklink /D c:\paratxt "C:\Your\long\path\to\paratext"
In this example, mine is:
mklink /D c:\paratxt "C:\Users\corey\OneDrive - SIM International, Inc\Documents\SIM\Wolofal\My Paratext 9 Projects"
A new symbolic link folder will appear at c:\paratxt.
Then as above your Target box will be:
"C:\Program Files\PTXprint\PTXprint.exe" -p c:\paratxt
