It actually launches and works.

Pre-flight checks

• I searched existing issues and didn't find a duplicate.
• I'm running this fork (frankea/Whisky, confirmed via Whisky → About) — not the archived original that the default brew install --cask whisky installs.
• I confirmed this is not a game-specific compatibility issue (use the other template if it is).
• My issue is written in English so all maintainers can read it.
