What causes this issue

Wait for it… Build errors!

I take it this is for Android? If so, try exporting the project and building from Gradle.

Another issue with Android (if that is what you’re targeting) is the miserable Java-based toolchain. which also requires SDK license acceptance and everything else to be just so otherwise it uselessly throws a pout and fails. Make a fresh blank project, see if that can build. If that cannot build then at least you know it’s a toolchain problem, NOT your own code.

There might also be more-useful messages further up the console log.

I fixed this issue by removing System.IO from my scripts, it’s a bad solution though because i can’t use file.delete to delete a save file, btw I’m building standalone.
any thoughts
