The `Error : Build failed : Couldn’t cache details for ‘’.` error message indicates Designer couldn’t find an audio file required for the build - and worse, that it couldn’t even find the name of the file that’s missing. You’ll have to check your project’s banks and events for missing files and files with missing names.
