[Bug]Hag won't spawn

I reached the hag's lair, entered the room with mayrina cage, the boss fight cutscene plays. Then nothinf. No hag. I am free to do whatever, if I free mayrina she will keep running away and if I manage to catch her sometimes she will talk sometimes she won't, the dialogue options say that the hag still lives.

The quest does not complete at all. I read that this was a bug before, but she was simply invisible and if you hit her with aoe you can see her but she won't fight back. Not for me, for me it's like she ceased to exist. I threw so many alchemist fire and doe so many aoe spells including faerie fire.

I have no idea what to do, this really bummed me out. I was excited to see the hag since I skipped her 1st playthrough. I am afraid this is caused by one of the mods I installed, but disabling all mods then going back before the cutscene still won't make her spawn.
