I've been playing Fortnite over the Switch for quite a while. Since shortly before the last update 15, I can no longer play because I only get the message "The software can't be started". However, my account is properly registered and linked to the parent. Despite everything, nothing works anymore. Can someone help me or do I really have to throw everything down and reinstall?
I think reinstalling the game would be the best option. Definitely try this out.
If it doesn't work then, you can contact Epic Games Support and get further help. You can contact the support here: https://www.epicgames.com/...upport-c93 (at the bottom: "Contact us"). If you have any questions, please let me know.
Beautiful evening!
