If you're on console keep trying or create a new Xbox/PS4/PS5 account and make new runs. If you're on pc and you still have your save files somewhere, you can: check if you have anything that could be invalid data (Ex: a gesture you can use as a consumable item) and discard it, if you can't discard it install Cheat engine and a ds3 cheat table and search for a command to discard anything. Once active you can discard the invalid stuff and create a new steam account, activate steam's family share system, create a new character (to create a DS30000.sl2 file) and install "SaveMerge" (should be https://nexusmods.com/darksouls3/mods/409 ), then open it and drag your old character/s to the right/left part and the new one to the opposite side. Now copy the steam id of the new character file and paste it where the old characters files' steam id is; Click save under the old characters and delete your new character's DS30000.sl2 file and replace it with your old DS30000.sl2 file where your old characters are and it should be done.
Sorry if I explained it badly but it's easier than it seems, it should take around 5-10 minutes. If you don't understand something, ask me or google it.
If you're on console or you don't have your old files anymore it means that I wasted 5 minutes of my life but I hope at least that this may help someone in the future.
