FortniteClient-Win64-Shipping.exe Entry Point Not Found error

I found a solution that worked WITHOUT REINSTALLING

Locate FORTNITECLIENT-WIN64-SHIPPING.EXE (C:\Program Files\Epic Games\Fortnite\FortniteGame\Binaries\Win64\FORTNIT ECLIENT-WIN64-SHIPPING.EXE)
and delete it. Also delete FORTNITECLIENT-WIN64-SHIPPING.EXE.Local which is in the same folder.

Open the Epic Games launcher and near the “Launch button” shows a settings icon – click it. In the popup click the option “Verify”. Note this process takes a few minutes but it should work.

Works for me, hopes it does for you.

NOTE: Path may be C:\Program Files x86\Epic Games\Fortnite\FortniteGame\Binaries\Win64\FORTNIT ECLIENT-WIN64-SHIPPING.EXE
