I’m adding my experience to the rest of you. I started getting the error occasionally in act 3 and got stuck at Raphael’s fight with no more possibility to save.
After several attempts the following day I did manage to save three more times and then no more.
Right now I currently have only 4 saves and I keep getting the message that I must delete or overwrite my saves since I reached the maximum for the campaign. Overwriting just gets me the failed saving with 544 error message.
I thought that while waiting for this to be fixed I would start a second run with a different character but it seems the number saves limit is shared so I am unable to save even once with the new run.
It’s basically impossible to play the game anymore and it’s worrying to see some people are in this situation since months…
I also tried to enable cross-save but it keeps saying my email and password are not correct…they definitely are because I am able to connect to the website through my phone without any issue. I am not sure what is wrong with the PS5…
