I GOT THE ANSWER!!!
After literally hours of looking for a fix i finally found it, Okay so first your going to want to find your epic games launcher
Then your going to right click and go to properties once in properties your going to go to shortcut then go to the box that says target.
Once there type in -SkipBuildPatchPrereq making sure to have the space after the already existing target so it should look something like this
“C:\Games\Epic Games\Launcher\Portal\Binaries\Win32\EpicGamesLauncher.exe” -SkipBuildPatchPrereq
I really hoped that this helped you
