Cant compile project on 4.8

Hello everyone,

So I started to add code to my project and when trying to recompile I keep getting this error, it doesnt really give much detail on whats going on, I tried everything I could do but to no avail just wondering if anyone else has some input on the situation.

This is the error

Thanks everyone!

Have you tried to force rebuild the solution by right clicking on your .uproject file? I tend to do this between versions of UE.
