Border Lands pre sequel main story not working

HI all,

first time posting here. I’m playing as Jack level 51 True Vault Hunter Mode on Xbox series x. For some reason, after a certain point (I can’t remember when) but I only have side missions. The story missions are gone. I can’t continue the story. I have completed all available side missions in hopes the story missions would continue with no luck. Does anyone have any suggestions on how to fix this?

Make sure you are in TVHM not in Normal mode. What was the last story mission you’ve done?

user error lol
looks like i had killed the sentinel and completed the story. I
