Epic Games Launcher Not Letting me Play Fortnite

Ok so a couple of days ago I installed a new HDD on my PC and moved my fortnite onto it. Everything was going fine until it kicked me out of a game and said I needed to verify my game files. Then the epic games launcher started to reinstall fortnite on its own. When it got to the end of the install it said that the installation was corrupt. It gave me error code SI-bv04. Which ocording to Epic themselves means My HDD is using the wrong file system and should be on NTFS (which it already was on). Or that I have ram issues. I have ran windows memory scanner and memtest64 and they both have come back fine. So now its giving me a error code that doesnt even apply to me. I tried reinstallling the game proabably ten times. Heres another thing to mention. Everytime I install the game I know for a fact that the game files are installed on my PC but the Epic games launcher won't acknowledge that they are installed. I will attatch a photo for what I mean. Here are the things I've tried to do. I formatted my HDD, I rebooted my PC. I deleted everything that has to do with the epic games launcher and reinstalled all of it, I have contacted epic games and they of course are no help. If anyone has any idea on how to make epic games launcher recognize that I have the game installled please let me know. Thanks!

Edit: I also forgot to mention that The launcher will start to download crazy amount of GBs (120+) even though the game is only around 80 or 90.

EDIT: Apparently it was a RAM issue.
