I'm still getting the .pck error, so i guess the fix didn't work:
"Error: Couldn't load project data at path ".". Is the .pck file missing?
If you've renamed the executable, the associated .pck file should also be renamed to match the executable's name (without the extension)."
Also, like another comment pointed out, the mushroom effect never seems to end even after multiple minutes.
Edit: i kept trying a couple of times and it seems to be about a 50/50 chance to work
