It’s possible you are missing the Switch extension package for UE4. If you [register your project](https://fmod.com/profile#projects) on your FMOD profile page and [verify](https://fmod.com/profile#permissions) with Nintendo as a Switch developer you should be able to access these files on the FMOD download page.
