I just upgraded from Emacs 29.3 to Emacs 29.4 about 30 minutes ago with no changes to my configuration. However, I have found that one of my most beloved features seems to be broken. I often use `M-x restart-emacs` to test how different configurations affect my startup time. However, right now the command just safely shuts down emacs without starting it up again. Given the simplicity of this situation, I believe this is a new and original bug and not a user error. Is there anything I can do to fix this?
