Another user stuck in the Forest Array cutscene/flashback

PS5 pro. Latest patch. After entering the Rehabilitation Wing and triggering the initial cutscene, I'm sent to the Tanalorr flashback. Santari and Dagan chat for a bit, I'm zapped to a new area, and I'm stuck there permanently. Santari and Dagan should spawn again to resume their dialog, but they don't.

Have tried restarting, turning down graphics settings on both the game itself and my console, reverting to my latest cloud save, even the "aggro enemies and remove your map beacons" ritual that one user suggested. No change. Can't progress.

The game is broken, and judging by the several 6+ month old reports of the same issue (along with the Singing Ruins door), it's pretty clear that the game is abandoned and unsupported at this point. Maybe it's wishful thinking, I'll still post this here and hope that someone's found a functioning workaround, or (even more wishful thinking) maybe we'll get an official response someday.
