Problem fixed!
Right-click on your Epic Games launcher desktop shortcut Select “Properties” In the line labeled “Target,” add the following to the very end (after the quotation mark): -SkipBuildPatchPrereq It should look something like this: “C:\Program Files\Epic Games\Launcher\Portal\Binaries\Win64\EpicGamesLauncher.exe” -SkipBuildPatchPrereq
Click “Apply” Double click the shortcut to run the launcher and try again and make sure to add the space between the quotation and dash

It worked to me! My error was LS-0019-IS-0001. Thank you so much!
