My brother and me bought the game yesterday. Don’t know about this bug. Wrote an email to the support team, but poorly only the classic answer like restart ps5.
Any ideas to fix it without the help of the support?
Everytime he fights, the screen freezes for about 7 seconds, the it goes on for 3 seconds, then another 7 seconds of freeze. After a few attempts the game freezes completely and over an hour of playtime is thrown away. Please help. 
P.S. if support read this, please check my latest mail. Thank you.
It’s horrible and unfortunately not much going on about it.
