No creative map within Fortnite

Hello. I keep reading that we should be able to go to “Games By Epic” or maybe it’s “Epic Games” from the maps selection, but I can’t see it. Also Unreal Engine itself keeps giving me a slew of errors when I start trying anything there. I can get in and have started a map but I edited something and now I can’t load the map to play test it and I have no idea what is wrong. Any help here?
