If this thread is about the ‘failed to fetch profile information’ error when trying to log in to the game, there’s a possible workaround but it will potentially delete your H3 save games and resets all settings to default. It basically created a new local profile for you on your console.
On the PS5 menu, go to Settings > Storage > Saved Data and then delete the H3 ‘profile’ stored there. It’s a similar path on PS4.
Deleting this file won’t affect any of your progresson, only the ‘local’ files.
