Build Failed - Lots of Errors

My build keeps failing, this issue seems to have arisen as I started to remove a lot of duplicate or unused assets (The project was a mess when I got it) that were in the UE project. As you’ll see in the Log I’m getting 78 Errors, and 785 warnings. I can tell that the warnings appear to be the assets that I deleted, though I have no idea how to clear or remove those warnings since they should no longer be referenced in the game.

Along with the asset warnings I am receiving warnings that say they are unable to find variable and functions. At first I thought this might have to do with the plug-in that i Was using but not all of the warning were isolated around the same plugin.

I created a second instance of the project and decided to just deplete all uses of th variables just to see if that would reduce the warnings / errors, and somehow it still has the same errors as before still making references to the same variables even though they don’t exist in the project.

I am at a complete loss for words. It looks like things are cached or referenced somewhere but I have no idea where and it appears to be negatively effecting the build…

Any help would be GREATLYappreciated!
