Departs in the Arena of the Chosen (on the Nameless Island) (Divinity: Original Sin 2)

I pass the arena, finish the dialogue with Dahlia, and then give control of the character. Then auto-preservation begins, and at that moment the game takes off. If you disable auto-preservation in the settings, you can go further (passed to the ship), but then flies again while trying to save. Tried two versions of the game (gog and repack xatab) - carried the save from one to the other. Definitive version, the last patch. There are no third-party mods. What can be done in this situation? It would be a shame to tear down the save and start over, especially when I went this far
