Part 1: Why Battlefield 6 Won’t Start or Launch

Before you reinstall the whole game (again), here are the most common reasons it won’t start:

• Secure Boot not enabled or misconfigured—Battlefield 6 checks your Secure Boot state for anti-cheat.
• EA/Steam launcher conflicts—Launching via the wrong client or broken cache causes silent fails.
• Background apps or overlays—Discord, MSI Afterburner, or other overlays can freeze launch.
• Corrupt shader or DirectX cache—You might get a black screen or “nothing happens” issue.
• Network check fails – The game hangs during server authentication, especially if routing is unstable.
