I changed the password to my locked photos and now it says theyre locked by different google account

[idontevenknowwww]

I changed my password to my locked photos and now the thumbnail to all of them shows up as a grey box with a triangle and exclamation mark and when i tap on them it says they are locked by a different google account, even though i dont have another one, so i have no idea how to access them.
Ive tried restarting phone, changing password to the locked photos, removing google account and restarting phone then adding it again, accessing them while no account is logged in, connecting with pc and checking gallery there where it says the file is either damaged, wrong or too big... and nothing. I can delete them but i cant view them. The file endings has .jpg.dm so i assume theyre encrypted or something. Help would be exrtremely welcome as the photos are important to me.
