### Expected behavior

When I run the doom script with the `install` flag, it should successfully install.

### Current behavior

Following the instructions on the Doom main page, I am unable to download and install Doom.
When I run `doom install`, the script fails at the line "Building straight":

Creating process pipe: Too many open files

This occurs with installing via MySys2 and with Powershell. For MySys2 I installed Emacs using the Pacman: ` pacman -S mingw-w64-x86_64-emacs`. For Powershell, I installed Emacs using `choco install emacs`.

The docs recommend using WSL, unfortunately, that is not an option for me since my workplace disables WSL on our Windows machines.

### Steps to reproduce

1. Install [MySys2](https://www.msys2.org/)
2. Open a MySys2 shell and install Emacs using `pacman -S mingw-w64-x86_64-emacs`
3. Clone Doom emacs to `C:\[USERNAME]\.config\emacs`
4. Run `C:\[USERNAME]\.config\emacs\bin\doom install`

Note the issue reproduces even with the default config generated by the install script. There is no need to create a custom config to recreate the issue.
