I spent 20+ hours creating a game.
I am an idiot
So I reset my computer and I only saved the shipping development of the unreal engine file
I didn’t save the editable file
Is there ANY WAY that I could open the shipping build of the game in unreal engine?

You can open the PAK file, which is what the engine does when the game starts.
