If I use the latest Synthesis UI (version 25.4), the Settings window doesn't open. And if I use the latest Mutagen version 0.41.0, it doesn't compile. I have to choose "Match" for the UI and Mutagen, which sets the UI to 25.0 and Mutagen to 0.40.0. But once I set those and run Synthesis it completes successfully.
