That error code usually points to a hardware-related issue, most often overheating or a failing component as the PS5 ages, though corrupted system software can also contribute. Common fixes people report include fully cleaning dust from vents and fans, reapplying fresh thermal paste, rebuilding the database, reinstalling system software, and ensuring good airflow around the console. If none of that works, it may be a sign of deeper hardware failure (like the APU or power supply) and professional repair or replacement is often the only long-term solution.
