The issue with epic is you need to visit two places, one place where the manifests are kept on c drive for epic client to read, and other place is where you place your games at, but if you made more places you put your games, then that more places you need to look for. Find the game folder you want to reinstall (get working) and rename it The epic games launcher also causes my computer to freeze like crazy and my pc specs are pretty decent
