  • Connect your DualShock 4 or DualSense controller via USB cable and press the PS button.
  • Select “Clear Cache and Rebuild Database” and then “Rebuild Database.”
• Check Storage Space: Insufficient storage can cause applications to crash. Go to Settings > Storage and free up space if needed.
• Reinstall the Game/Application: If the issue persists with a specific game or app, try deleting it and then redownloading it from the PlayStation Store.
• Check for Overheating: Ensure your console has adequate ventilation and is not placed in an enclosed space. Clean any dust from the vents.
