So, the quest asks you to interact with an altar, it then plays a cutscene and you are teleported to an arena to fight the Douksini, the first time I have tried to finish the quest, after skipping the cutscene (this is the second time I'm doing the LOML questline) I did not regain control of my character, I could not attack, I was stuck in place and the Douksini was attacking me, at first I thought this is part of the cutscene so I have waited for about 5 mins but I still could not control my character and the Douksini could still not attack me, so I have swapped characters in order to forcedly reset and then swapped back, after interacting with the altar again and skipped the cutscene again this time I have gained control right after the cutscene ended but I have realized that I could not damage the boss with any attack, it can still damage me but I heal the damage immediately somehow, his hp bar is not moving even after attacking him for about 10 mins and no damage indicators appear (back attack, crit, miss or immune)

I have tried everything to remedy the bug, I have forfeited the quest and accepted it again and it was still bugged, I have tried not skipping the cutscene, I tried killing myself and the "Escape" option in the menu to reset my character, to no avail.

I'm at a loss, in the image above you can see me attacking the boss, after already attacking it for several minutes, no dmg indicators (I have them on) the hp bar is still full and I also did not seem to take dmg from the attack
