We've been having issues here for 6 months, same on playnite, it's just Sony being an asshole with all those security measures.

You can try this method: note that it may not work the first time, just keep trying.
If it won't work don't panic, you can always try to edit the code to make it work again, just follow these steps.

I presume you want to connect your PSN account for enabling cross saves on the witcher, but note that you don't have to do that, you just have to link your GOG account with your PSN one directly in game, i think it will show up a qr code to login first time you open the game after the update.
