Svsona, Fermosa Fembra bug

[SolelyMK]

So today I faced a really serious problem with Svsona, Fermosa Fembra boss
To be more exact, I can't continue my game after beating this boss
I guess, it's important to mention, after I finished Sinodo, Hymn of the Thousand Voices I accidentally activated the spear girl(don't remember her name) and she appeared during the Svsona, Fermosa Fembra fight(in fact she's dead we can see her dead body on the flour).
How can I fix that, I really enjoy this game but I don't want to restart it

Does my fix work for you? https://steamcommunity.com/app/2114740/discussions/0/3816291531978767852/#c3816291531981992114
