Problem with the extension of Taifun

When I use the extension Package tool (version 2) from Taifun, my app is not built and I get this error message.

Kodular is unable to compile this project.
The compiler error output was

does anyone have an idea?

you asked me the same in PM
and my suggestion was

What happens, if you create a new project, add the extension and build the project?

your answer was

when I create a new project and use your extension, the project is created

which means, the extension works fine… you have to search for the bug somewhere else

as a start, remove all other extensions and try to build again
