Infinite Loading Loop on Long Conversation (2+ Months of Lore / High Context)

Issue Description:Context:I have a single conversation session that I have been active in for over two months. It contains an extensive amount of roleplay data and world-building (hundreds of thousands of words).
The Problem:When I try to open this specific chat from my history, the interface enters an infinite loading state (the spinning wheel/loading bar never finishes). The page becomes unresponsive, and I cannot scroll or export the text.
Steps Taken:Cleared browser cache and cookies.Tried accessing via different browsers (Chrome, Firefox, Safari).Tried accessing via mobile device.The issue persists only on this specific long-running thread; new chats load fine.Request:Is there a way to retrieve the raw text or a JSON export of this specific session? I have 2 months of creative work trapped in this thread andcannot lose the data.

this is the data https://arena.ai/c/019d76c2-00a5-710b-9694-e67552007276

Start with the linked arena.ai conversation and reproduce the loading failure, comparing it with a new chat that loads normally. Trace the history-conversation loading path and identify how this long session is handled; done means the conversation opens responsively or its raw text/JSON can be retrieved.
