MacVim opens from Terminal (mvim) but does not render interface from Finder

Comece comparando o MacVim iniciado pelo script mvim com o MacVim.app iniciado pelo Finder, usando as personalizações relatadas de .vim/, .viminfo e .vimrc como as principais variáveis. Reproduza o comportamento de janela ausente com a configuração do usuário e, em seguida, identifique qual personalização ou diferença no contexto de inicialização impede a renderização da janela do editor e verifique se as inicializações pelo Finder funcionam sem remover configurações não relacionadas.

Huge version with MacVim GUI.

This is macvim: 8.2.2164,169 (auto_updates) installed as a cask from Homebrew.

When I launch MacVim using the mvim script from Terminal, it launches the app and renders a GUI window. Everything is as it should be.

But when launching from Finder (either Cmd-space and typing MacVim.app, or double clicking the app bundle from the Applications folder, the app runs; it creates an icon in the dock, it presents a menu, but it doesn't render a window for the editor. Cmd-O opens a dialog to select a file to open, but opening a file does not render an editor window for the file. The Window menu does not list any open app windows. It's running and responding appropriately, but not rendering a window when launched from Finder.

I've seen this behavior in several macOS releases now over the years. It's sporadic. When the issue occurs, it's frustrating and I move on, but at some point I switch back to the MacVim task and open a new window, and it just works as if there was never an issue.

As an experiment I backed up and removed my existing .vim/, .viminfo and .vimrc which are customized. Afterward, MacVim launched correctly (rendered windows) from Finder. I'll review settings but it's not clear to me why a customization would cause failures running from finder vs. running from start script in Terminal.
