* This test ensures that the VM gracefully handles an sb3 project with
* a missing sound. The project should load without error.
* TODO: handle missing or corrupted sounds by replacing the missing sound data
* with the empty sound file but keeping the info about the original missing / corrupted sound
* so that user data does not get overwritten / lost.
