My PlayStation 5 might be cooked

So last night I was playing a game, and this game doesn’t have lag. But last night it did for a bit and then it froze. It wouldn’t let me turn it off, I tried to manually turn it off, and it still wouldn’t turn off. But then after like 15 minutes it turned off and then turned on again. (I assume it turned on again because I pressed the power button a lot. But still don’t know if it did it on its own) while it was turning on it sounded like it died. it went from that higher pitched sound, to lower until it didn’t make sound. After that it wouldn’t let me turn it on, please if anyone has any kind of knowledge regarding this problem, please comment, your answer will be heavily appreciated.
