Possible issues with my PS5

Hello y’all,

today I ran into an issue with my PS5. It just turned off while playing cod 2 times. I already ran into this issue last year once but after that it didn’t happen anymore. I opened it up today and cleaned it (just got the 2 plastic sides and the fan out to clean), put it back together and now a few hours later when I decided to play it happened again. I don’t really know if it’s the electricity or really the ps5 and I don’t know if there is any way to check why it happened because I don’t really know much about this stuff.

I‘d be happy if anyone had any tips for me or probably had the same issue and knows some things I can try. Thanks :)
