It's not just the dungeon, it's everywhere. I've been kicked to orbit from the Helm, the dungeon, Savathun's Throne World, e.t.c... I'm on PC but my mates are getting the same error on PS5, from everywhere as well. I kept trying different spots thinking it might just be a dungeon code issue. It's not you it's happening everywhere, all my Steam friends are currently losing their minds at Bungie again over on a reddit thread. Bungie must have broke the game again trying to introduce the dungeon. It happens, Hopefully it's fixed sharpish and not some catastrophic mistake that will take forever to fix, I've been playing all day waiting for the dungeon to hit. Grrrr. ;)
