Unable to open new window

Hate to open this issue as I have no clue how to reproduce, and I currently have it fixed...for now...

Occasionally when I attempt to open MacVim, I'll get a single icon in the Dock for it (and the menu bar), but no window. It doesn't matter if I'm trying to open a blank file or passing in a file to open -- typically from an external app like Perforce/P4V. If I try to File > Open... and select a file, it will close the app down.

I tried looking in ~/Library/Logs for anything, but it doesn't look like it's writing anything there. At least not that I could find.

The only resolve I've found is to close the app, delete ~/viminfo and ~/.vimrc (or just rename to something like ~/vimrc), reopen MacVim. Then I can bring my ~/.vimrc back and things work fine again. For awhile.

I'm currently on 8.0.1420 (144), but I've encountered this on past versions as well. Usually my first step is to make sure I'm on the latest release. Let me know if there's something I should do now while it's still working to prep for the next time it happens. Or what I should look for next time it does.

Comience revisando el comportamiento de inicio y de File > Open de MacVim que se ha informado, incluida la interacción con aplicaciones externas como P4V. Compare el comportamiento cuando ~/viminfo y ~/.vimrc están presentes con el comportamiento cuando se les cambia el nombre temporalmente, y recopile diagnósticos durante la próxima aparición. Se considerará terminado cuando se disponga de una causa reproducible y de una solución verificada o de una guía de diagnóstico clara.
