Serial Size Mismatch UEFN

Everytime I load Unreal Engine Editor for Fortnite, it attemps to load a Project that I was working automatically on then promptly crashes every single time I load it up. The screenshots below show the crash report, the first two are in the same line, I just could fit all of it in one screenshot so I split it into two. The reason this is happening is because I set it to that everytime I load up UEFN, it auto-loads the last project I worked on, and I think that the project is bugged. I tried quickly going into some settings when I loaded up the application but I wasnt able to click or select anything when I did that, it would just show that it was loading my project then crash without letting me do anything in the app.

Here is the crash Report:
Assertion failed: [File:D:\build++Fortnite\Sync\Engine\Source\Runtime\CoreUObject\Private\UObject\LinkerLoad.cpp] [Line: 4573] /MyProjectE/ExternalActors/MyProjectE/D/L6/QRUTQX4BVWMTIGDBLIJAKJ: LandscapeComponent /MyProjectE/MyProjectE.MyProjectE:PersistentLevel.Landscape_0.LandscapeComponent_10: Serial size mismatch: Got 46999, Expected 51795
