How can I fix this in Fortnite?

I need help fixing it. I went to Fortnite for the first time to start it, there was a patch available. It said I have to restart Fortnite. I did but I always came to the patch display. How can you fix it?

You have to wait in the Epic Games launcher until the update has finished loading

Thank you for the answer. I will try it

With pleasure.

If you have further problems please let me know

Should I just press okay because that is not possible

Yes

But I can't press on it

Wait a minute, how I start Fortnite

Thanks for your help
