I looked into it, no idea what happens. When I play tested the game regularly on the preview feature of GDevelop it used to run fine. I was in a rush when I exported it because it was 1 hour before the deadline and 5 in the morning in my time zone so an honest mistake might've happened. Sadly I can't do much more, I've lost the project file in that mess (even searched in the bin unsuccessfully). So the only fix I could do is building the game back from the ground up using the textures and soundfiles I've got left and thats not something I'm willing to do again for a quircky kinda rushed 30min long game. So I'll do this: take it down, take the L, try again another time and in the meantime try to see why the export failed. And if I ever come across the project file again I'll fix it and reupload it back onto my public games but in all honesty thats unlikely. Have a good day and sorry for the inconvenience!
