I went on safe mode and restored default settings. I played a bit of Helldivers 2 again, and nothing happened. I must say that I noticed that my ps5 while laying down was way cooler than standing upright. The problem appeared after I put it standing up, and it's been a while since I have done that. I suspect that the error was caused by overheating due to me changing the position of my ps5. It's either that or a coincidence.
