I’m playing on Xbox series X and have the same issue,
On solo play and private server, the game freezes then after a moment it crashes.
When trying to log back in it loads through the first load screen and then freezes again at the second one while loading the local assets for the volcanic area of the Siptah map (Ash Lands).
First noted on PvE server Into The Bad Lands, Temple of the Loon
Tested on solo game using Admin Teleport to Fractured Citadel.
Tested on PvE-C server No Drama 2 traveling south from Leyshrine of the Birdmen.
Issue first noted after download of most recent update.
