[Solved] How to fix Fatal Errors in UEFN related to Graphic Cards and Shaders and Derived Data problems

Thank you again for the help, unfortunately what should be seconds is a nightmare for me, when I re-installed UEFN I saw no area that asked where it should go so I let it install.

My PC is an odd setup my brother in law did it, I have a S/E/F drive
Seems UEFN and FortniteGame are on F (they used to be on C but something kept eating into the HD space so they are on F now)


So that’s a screen of where UEFN is located but nothing like the shortcut at the top.

I added that at the end so it looks like this
F:\Fortnite\FortniteGame\Binaries\Win64\UnrealEditorFortnite-Win64-Shipping.exe" -d3d11 -sm5 -DDC=None

It just says something wrong with the shortcut - really sorry I am not a critical thinker and can’t understand or work out a way around it, I did try the link with a C at the start but no good plus UEFN not on my C drive.

Really sorry to be a pain, hoping you know of a simple solution

Thanks again for your time
