Stuck on Chapter 8 - elevator will not open

I've been playing the Dead Space remake on PS5, and have reached a point in Chapter 8 where I seemingly cannot progress. There is an elevator that says "authorized personnel only" that simply will not open to allow me to take it. Every walkthrough I've read says the elevator should open (with a monster inside), with no special tricks needed to make it open. I have no save points further back to allow me to get back to that point and don't want to start over hoping it doesn't happen again when I reach this point. Is there something I'm missing?
