Unlocking stasis subclass is bugged

[ElevenEleven]

I've played through all of beyond light on my warlock and gotten to the final mission where you ascent the stairs and interact with the ghost shell to unlock stasis however for some reason interacting with the shell does nothing, and I cannot get the subclass. This worked on my hunter, so I have no idea why I can't unlock it on my warlock. I should note that I picked the game back up after TFS so my first time playing through beyond light was after I had already gotten prismatic on both characters, not sure if that's contributing to this but it still wouldn't make sense if it worked for my hunter and not my warlock. Anyone run into something similar?

I have the same problem right now, I got stasis on Titan and Hunter but I can't interact with my warlock. It's driving me insane. I don't have the beyond light quest mark, I can't anymore
