Hi @pulpeirodasilva. Thanks for the note.
Can you confirm whether you have moved any of the files from the game I packaged? This seems like a missing file error and should not happen as long as the files are kept intact.
Please try the source code on GitHub (Ren'Py 7.3.5) without removing or changing anything. If your SDK is Ren'Py 7.4, try the GitHub prerelease.
If you have any more questions, please feel free to reach me on Discord. My handle is lynn#9327.
