how do i get out of the bugged crow fight?

Help, im on a crowbell boss map in the endgame, the boss is invulnerable and doesn't change phases, how can i get out of the map? i don't want to lose my exp and restarting the game just puts me inside the map again, the town portal is disabled.

I saw in the bug report section that this is a known issue but, how can i get out? i feel softlocked, should i just kill my self and lose the exp?
