[PS5] I can't join the same party as my friend

[PS5]
When I created an account for another character, the stash was shared with the first account.

I'm not sure if that's the reason, but I can't join the same party as my friend, although it shows as me already joined in the system.

I don't mind deleting the account data, so I would like you to delete all of the data for this P-tyan#3979.

If it remains like this, I won't be able to play with my friends and have fun.

Please do something about it.
