I just gave it a quick clean, but I didn't go any further than removing the plates and trying to suck up dust out of the dust catchers. Gonna play more and see if the message comes up again. If it does, I'll get more thorough with the cleaning.Did you ever clean your PS5?
This happened to me when I played Miles Morales, console straight up turn off, no message. Turned out that PSU was clogged with dust making the system to overheat!
Every major release, I clean up my PS5 never had any problem afterward.
Yeah, was fighting the Morbol when my PS5 showed a message saying to turn the system off and wait for it to cool down. It's just weird to me because it's never come up while playing stuff like Demon's Souls, Ghost of Tsushima, FF7 Remake, or anything else.
