Stuck in Entaglement (no not the turret part)

[Yemo]

Hey, I im stuck at the part where the lights go out and they throw in those red flares. i killed all the guys (no big dead after the turret hell), but now I'm completely stuck i dont know where to go! the forcefield is up. do i need to push a button somewhere? or am i missing a secret vent?
I included screenshots of where I am
Thx in advance.

Isn't alyx with you there? She always goes first with me or tells me what to do...

 

[Yemo]

nope she isn't there...

How did you to the underground part in the first place? Without her you'd have to cheat your way down there, since the gate to the stairs is locked.

she opened it for me, but she didnt come with me. I went back and she is still there but doesn't respond when i try to interect with her, could this be some kind of bug?
