On PS4 and having the same issue. I've sent about half a dozen reports on the PS4 too.
It only happens in areas of intense combat. CZs, Resource Extraction Sites and Nav Beacons (especially Compromised).
I thought maybe it was my Crew member / SLF bay at first, since the NPC voice is already bugged and my Crew member doesn't say most of her scripted lines since the last update either (another known bug I'd imagine). But when I left the SLF Bay and my Crew member at port, it happened again, more than once.
EDIT: I also have 120mb/s internet speed. It's not anything on my end. ED in general has been having lag/stuttering issues quite a bit since the last update. I have a feeling I'll just have to bite the bullet eventually, and buy a Pro, or even a PS5, for ED to run smoothly again. All the changes to the game (over the past year or so) have made it run progressively worse on the standard PS4.
