### Issue description

When the project loads in editor, all the settings defined in project settings will be loaded over the default values, but when running the game nearly 95% of them will be ignored resulting in just loading the default settings.

here it's just loading only 4 variables from project setting and i have added the fifth in this pull request https://github.com/godotengine/godot/pull/80151
