bug#38031: 26.3; Trying to invoke the macOS File Open window causes Emacs to crash on macOS Catalina

[Michael Dixon <dixius99@gmail.com>]

Thanks so much everyone.

I was able to build from source. I had the same libxml/tree.h error as Nathaniel.

The crash error I got was the same, but before I waste any more of your time, I wanted to share that I set up a Catalina virtual machine and installed via brew cask and did NOT get the crash, even without providing full disk access to ruby, Emacs.app, etc.

This leads me to believe it my problem isn’t specific to Emacs, but rather something else unique to my environment, though I can’t think of what that might be.
