Broken Launcher, "Emacs failed to launch!"

[prahaladramji]

macOS 12.3.1 (arm64) Emacs 28.1-2 (installed using brew install --cask emacs) doom-emacs configuration framework.

Emacs works fine, when launched in a terminal either with emacs -nw or emacs both work well. But launching using the Application launcher (the new rust launcher) fails with the below error.

Emacs failed to launch!
expected value at line 1 column 1

FYI v28.1-1 package worked, but the recent commit/change from 2 days ago broke this.

I am seeing the same issue. 28.1-1 had the issue where the dialog would show after exiting from Emacs. Now it happens when you run the launcher from the Dock.

Here is the screen I get

By any chance does your .bashrc/.profile/.zshrc/etc print to stdout? I suspect it does and I didn't account for that since mine happens to be silent.

I'm creating a fix now.

[prahaladramji]

In my case, during a successful load, zshrc does not print to stdout, but since i load tmux and also a few tools during startup (pyenv, nvm, ohmyzsh updates) do tend to print to stdout or stderr during startup.

I should potentially seperate the start sequence based on a login shell vs interactive shell.

Thanks for the fix.

[mnsanghvi]

I do not have anything echoing or printf'ing in ~/.bashrc, ~/.profile or ~/.bash_profile.

New build works as expected. Thank you.
