If Borderlands 4 won’t start on your PC, the most common cause is Windows or antivirus software blocking the game’s files. Follow these steps to whitelist the game executables in Windows Security, Windows Defender Firewall, and (if installed) any third-party antivirus. This ensures the game has permission to run without being blocked. Thankfully, it’s pretty easy to fix the ‘Your Settings Have Failed to Save’ error despite its annoyance.
