I experience the same issue too and it only occurs with fC26....I have so many other intense graphics games too
I did have this problem until I read that the PS5 should not be used standing up. I did the whole cleaning process and removed all games only to find no change. The CPU gets hot and the liquid silver heatsink then moves to one end due to gravity. I had to watch a video and buy some liquid heatsink ( £15 ) and about 1 hours work. I was sceptical but it worked perfectly and i now use the PS5 in Horizontal only.
