Game works in preview but not when exported as apk?

Hello again, I have a problem where my game works perfectly fine in the preview but after I export it as an apk all I get is a black screen. What could be causing this problem? I've tried minifying and not minifying the script but I still get a black screen for both

Project file

drive.google.com/open

The project uses images which are too big. E.g. Wolvus has a 5339 x 3006 image. This is larger than the maximum texture size on many devices, so the project will fail to load on those devices. Make sure all images are 4096 pixels or less in size.

This happens often enough that the next release of C3 will warn you when exporting with such large images.

Thank you! I will keep this in mind.
