It looks fine and when I clone the repo into another directory, it works. When I diff the files on the good file and the bad one, they are the same.
I figured it out
The project.b4a.meta file has
VisibleModules=6,98,99,100,101,102,16,44
And I'm guessing that some of these modules were removed from the project and the IDE has a problem with that. If I change this line to
VisibleModules=6
It loads correctly.
