Offline player mode goes back to the character creation screen

Thank you for providing the requested details, we’ll register the issue for our team to look into.

Just to get this bit of information out of the way, even though it might seem obvious it could possibly result in the reported behavior, do you have multiple accounts on your PS and were you ever logged into another one other than your main during this process?
Lastly, have you tried the restore licenses option or even to rebuild the database?

Should you recall any additional steps that might’ve been taken from the reinstallation to the reported event, such as whether you’ve accessed the game from another console, feel free to share them with us as every bit of information helps with the efforts of replicating the issue.
