I need help in fixing my cook errors, this is my first project ever in unreal (HELP)

Hello:
I see a lot of people trying to fix “Cooking Errors” but not giving the answers…
\

Is this something that people are preventing from sharing

Is it “Exclusive” just for a few fortunate ones?

I am getting to a point of “Giving Up”

Is there someone out there that can help?

Can I hire someone that knows to actually help me?

How much would it cost me to be able to package my game so I can play it on IPhone?

Please…
