Hello @itarumaa, welcome to the forums!
We’ll need additional details in order to assist you in this matter, as this is not a common issue.
Do you recall any procedure or taking any steps with both the game and console that led to these issues?
Do you have your saves backed up on the PS cloud?
By online saves, do you mean that you’ve seemingly lost your character on official online servers?
Is your PS4 set as the primary system?
