Particular games tripping my console off

In my experience issues with particular games can indicate disk reader issues. Especially with older Playstation games. If you are able to download a digital copy of these games do so and see if the problem prosists.

If the games in question are downloaded rather than psyhical media ypu could be experiencing thermal issues I'd certainly look into the fans and heatsink.

There's a chance it needs new liquid metal thermal compound on the apu, which is risky if you don't know what you're doing, as liquid metal is conductive and if it gets anywhere it shouldn't be it has the potential to brick a system.

A factory reset of the ps5 could solve the problem aswell.

If all else fails support your local or mail-in repair shops they will most likely be equipped to diagnose and handle the issue.
