Problems using QuickDraw

General Usage
1

I saw this package/talk on how to make deployable stand-alone Julia Apps using Quickdraw*:

here: https://www.youtube.com/watch?v=ruxYAY5_bfE

and here: Quickdraw: The simplest Julia package deployment system :: JuliaCon 2023 :: pretalx

The Github demo using minesweeper worked like charm, but when I tried to use a local project, I get this confusing errorfrom Pkg (and yes, the path does exist).

Any ideas?

julia version 1.9.3
This might take a while.

P.S. I hate the name “QuickDraw”, because (1) it is the name of an old MacOS API, and (2) it is non-obvious what the package does.
