PS5 frequent disconnect and unable to start game

I’m playing on a direct wired connections! I’ve cleared the console cache, deleted and redownloaded the game, called my ISP and got a new modem! I’ve updated the firmware on my Netgear Nighthawk XRM570! I have over 200gb of free space on my SDD! I’ve restored my console licenses and restored my console factory defaults! Still constant disconnects when I’m finally able to start the game! I’ve lost 10’s of maps and contracts due to game crashing while mapping or in heist and lost tons of sulphite trying to delve! This is my favorite game please help
