Moved Source Code Folder Causing Directory Issue

I downloaded the source code for Unreal just so i could expose some C++ only functions to blueprint, but I recently moved my folder containing the custom engine to a new location. Now when I try to open the project that was using the custom build, it asks me what version I want to use and all the functions I exposed to blueprints are giving me errors stating that they don’t exist.

Obviously this is a file path directory issue but i have no idea how to redirect my project to use the custom built engine from its new location.

I tried to open Unreal with visual studio (which i have almost no experience with) by pressing “Local Windows Debugger” but then it started rebuilding the entire engine and created a new folder with the old name and location where i had my source code last.

How can I redirect visual studio and my project back to each other or at least get visual studio to stop creating a new engine build at its old location?
