Failed to encode bank. A specific file could not be found. Unreal Engine events inaudible

As soon as I build my FMOD session all the FMOD events within Unreal become inaudible. Here is what FMOD says when I build.
Can anyone help?

Are you able to find any issues if you click File > Validate Project?

If not, could you open the logs (Window > Console > Logging) and build again? Are there any warnings in yellow or errors in red that you can see when a build is started?
