    Hi Michael,
    Thanks for your post!
    Sorry to hear you are encountering this issue! You have mentioned that you are running Windows 11 and I'm afraid Reference 4 isn't yet compatible with Windows 11, see our disclaimer here: Reference 4 compatibility with Windows 11 This, very likely, is why the app is exhibiting some unexpected behavior.
    For possible fix suggestions, I can recommend checking out our support article on the "Audio Playback Engine Failed to Start" error and see if that helps: "Audio playback engine failed to start" error in Reference 4 Systemwide
