help needed lightfall campaign bugged?

so i finished half a day ago the quest 16 SPOILER HERE ( it’s the emperor boss fight) and the whole quest line disappeared.at first i spend almost all the rest of day running around doing side quest and stuff in hope it will somewhat return but after watching a youtube video i saw that you have to go to zavala and ikora.

i visited both of them but nothing happened i tried as my last hope.also in the quest archive the is nothing i checked that too in case i did something by accident.

i tried to submit a ticket but i did not find any way to do it.im holding hope that im messing up on something cause im only 50 hours in and this game is weird but i could use some help right now
