Unreal Engine Won't Launch Internally

Hello,
My project will launch when I select launch outside of the engine. It compiles, builds etc., without any issues. But when I’m in the unreal editor and I click to launch it fails during the building windows executable. I can’t figure out how to resolve the lnk errors which are mostly lnk2001 and lnk2019. I’m assuming those are why it won’t launch inside the engine. Here are the logs -
