Iz, Deskaris middle fight bug

Hey, so i fought deskaris and when i reached 500hp there was dialogue, and i cant choose any of mythic options, they all red . I got into situation where i cant progress in a game in any way, i cant leave iz aswell. After the Abyss i talked to demon lord and angel, and i chose to become legend (prior trickter). After that i almost rushed to the main quest.
