Godot Version
v4.3.stable.official [77dcf97d8]
Question
My problem is similar to Project setting changes aren't always saved to `project.godot` when pressing Ctrl + S · Issue #55145 · godotengine/godot · GitHub.
When I change background color in project settings it changes only in editor, but when running the game background is color that was before.
When reopening the project background color resets to 2nd image’s background color.
