PS5 startup problem

[u/ginomercurio]

Lately, when I launch FC 27 with the console just turned on, my PS5 shuts down by itself. To turn it on, I have to do it directly from the console, which gives signs of life by beeping, but the blue light doesn't turn on. After trying a couple of times, my console turns on, displaying the following message, which usually appears when the console is running and the power goes out (note that this only happens once, usually as soon as I turn the console on). Once it reaches 100%, the console returns to normal operation. What do you think is the cause? (I'm attaching an image, I think it's understandable even if it's in Italian)
