An Instrument to unfold space and time bug

[Stri5r]

Hello

I have encountered a bug during the mission  space & time - Acquire the Rift anomaly modulator . After i get the modulator and open the first rift and climb up the security chief Vaillancourt is just quiet. Even when pressing x by speaker he says nothing so im completely stuck. Elevators closed cant leave the area. Please fix this unable to progress at all and been stuck for days. Ive uploaded a video of it from phone to imgur as the size was to big to upload here
