Window doesn't open when launched from the Dock or Finder

Steps to reproduce

1. Launch MacVim from the Dock or Applications folder
2. New window does not appear.
3. File -> New Window and File -> Clean Window does nothing.

I removed .vimrc, .gvimrc, .viminfo, and all plugins and the issue persists.

If MacVim is launched directly in terminal via /Applications/MacVim.app/Contents/bin/mvim, everything works as expected. Similar issue was raised in a Google Groups discussion.

Expected behaviour

A new window should appear when launching the app.

まず、Dock または Applications フォルダから MacVim を起動した場合と /Applications/MacVim.app/Contents/bin/mvim を比較してください。この issue では、これらのエントリーポイント間で異なる挙動が報告されています。記載されている MacVim バージョンを使用して macOS 15.0 でウィンドウが表示されない挙動を再現し、その後、アプリをグラフィカルに起動した場合と File → New Window から起動した場合に新しいウィンドウが表示されることを確認してください。
