First, try the easier shortcut to UEFN and add DX11 as an Additional Parameter
in this picture, copy and paste the line below we need to add Dx11 and sm5
to give -d3d11 -sm5 at the end of Target box
"C:\Program Files\Epic Games\Fortnite\FortniteGame\Binaries\Win64\UnrealEditorFortnite-Win64-Shipping.exe" -d3d11 -sm5
Now start UEFN from the Desktop Shortcut
Update remove the highly technical text as of 32.00 the control file .ini no longer exista
