Grasshopper Player (custom tools & wish list)

Hi, y’all! I’ve been diving into the forum trying to solve a problem I’m facing with GH Player and Elefront, and it looks like this thread is full of experts, so I’m hoping somebody has a solution or at least an explanation.
Is this simple issue where I am trying to export a file using GH player and the output is a file with 0kb, like this other user describes (with 0 answers :smiling_face_with_tear:):

Here is a screenshot with the script and the message:

It works smoothly when is not running by the player, I am exporting to my desktop, I have the latest version of everything and I am 100% sure that the file is not being used as it says in the Export Output.

Has somebody been there and done that?
