Fortnite closes after opening?

I want to open my game and wait until it opens and then immediately it closes again and I could open it again what should I do?

Childlock

Just read it closed

Check out bugs on youtube or ask support

Hmm maybe uninstall and install if you know your data maybe Fortnite has a customer service maybe your IP address has been banned (they are all guesswork) Try to log on to another device
