If you don't want to read I found my solution for PS5: Again the steps are. Go to settings-->go to system-->go to system software-->go to reset options-->go to restore default settings..then go through the reset process and bam it should work god willing.
hey there..im on PS5 and experienced this both in 25 and 26...i tried everything to fix it in 25 and didn't find a solution that worked for the rest of the game until i reset my PS5 to default settings. I know what youre thinking. This is not a full reset of the console...there's an option for that...DO NOT HIT THAT...otherwise you'll start with a brand new console with nothing downloaded...INSTEAD hit 'Restore Default Settings'...it will shut down your PS5 and reboot and act like you are opening a new PS5 but once you go through selecting your language, location, etc. all your games and all your saved progress is still there. It simply resets your network settings so that it's compatible with whatever the heck SDS does to make the game unplayable. I just tried this last night after experiencing this on 26 to my dismay and have finally completed two straight games with no problem or lag out on my end.
Again the steps are. Go to settings-->go to system-->go to system software-->go to reset options-->go to restore default settings..then go through the reset process and bam it should work god willing.
