Fortnite — errors & fixes

NVIDIA driver 591.74 crash + EAC errors

• Fortnite crashing on PC (NVIDIA driver crashes) — Update — or, if crashes started after a driver update, clean-reinstall with DDU — your NVIDIA graphics driver, then verify your Fortnite files in the Epic Games Launcher.
• Fortnite Easy Anti-Cheat error ('not installed' / 'Couldn't start the game') — Repair Easy Anti-Cheat by running the EAC repair shortcut from Fortnite's install folder (FortniteGame\Binaries\Win64\EasyAntiCheat), or reinstall EAC entirely.
• Fortnite 'Out of video memory trying to allocate a rendering resource' — Force DirectX 11 by adding -dx11 to Fortnite's launch arguments in the Epic Games Launcher settings — DX12 instability is the most common trigger of this error.
