Yesterday i wanted to fight Commander Zahlk to get the Achievement and to gain his Flaming Greatsword.
Prior to Release Version in EA it was possible to lure Enemies from the Nautiloids Helm Room to the Antechamber where the Healing Machine is positioned.
To do that i send in "Us", the Intelect Devourer (former Brain of Myrnaeth) to the Door of the Helm and a bit into the room itself. When Us got the Aggro from the enemies, i moved him back into the antechamber.
So i could fight everyone there and heal the whole party by using the Healing-Machine.
This was possible because Us could open the Door to the Helm, which is now not possible anymore.
To achieve it in Release Version you need to have access to other Forms of Conjuring, like f.e. Laezel Magehand or if you have your own. Might even be possibel with other conjurings like an Imp or Raven.
But it must have the ability to Fly to bypass the Door to the Helm.
No other Creature or Partymember should go near the Door, so it isnt automaticly starting the Autosave and then the opening cinematic for the Helm's Battle (Tolkien reference, lol).
As i couldnt use Us to kite all enemies from the Helm i tried to use Magehand and flew to the door.
But it didnt open up as i thought. Then i tried to just move by the door by clicking in to the dark not yet visible room of the Helm.
As Magehand is a flying creature, Magehand flew automaticly finding his way over the Door and started the Cinematic instantly.
The Glitch happened then without me doing anything more.
After the cinematic was done, Laezel was automaticly positioned directly in front of the Transponder Machine which the Mindflayer ordered you to use to teleport the Nautiloid out of Avernus.
See the Screenshot at my Steamaccount:

As far as i know, those kind of Glitches are very interesting for Speedrunners and maybe this and other areas in BG3 will have same possible soluttion to bypass content.
Larian Studios, its for You to decide to fix this or let it beas it is.
And for all the players: Use this Glitch at your own risk of missing a lot of content.
Spoiler END.
