Copilot Crashes in new Copilot versions when I try to open my two biggest Chats

For your privacy and security, I have covered the personal information included in your post. Please avoid sharing any personal or sensitive information publicly, such as serial numbers, order details, email addresses, phone numbers, or case-related information.

Hello Dag-Kristian Gjerstad,

I understand how concerning this is, especially when the affected conversations are among your longest and most important ones.

Since the chat titles are still visible but their contents fail to load on both the web and mobile app, this does not appear to be limited to one device. However, the visible titles alone do not confirm whether the full conversation content can be recovered.

Could you please confirm whether you are using Copilot with a personal Microsoft account or a work/school account? Also, do you see any message in Copilot indicating that your chats or content are still being moved or synced to the updated experience?

If this is a personal account, please make sure you are using the same account and the same sign-in method as before. You can also check the Microsoft Privacy Dashboard and use Export all activity history under the Copilot section to see whether the affected conversation activity is still associated with your account. Please avoid deleting the chats, clearing the activity history, or resetting the app before checking this.

Because the issue occurs across multiple platforms and affects specific conversations, please also submit feedback directly from Copilot and include the approximate date the issue began, the affected platforms, the chat titles, and any error message displayed. Do not post the conversation links publicly if the chats contain personal or sensitive information.

Please note that this is a user-to-user support forum. Contributors cannot access Copilot’s back-end systems or restore account-specific conversation data. If the chats remain inaccessible, please contact Microsoft Support so the appropriate team can investigate the account-specific synchronization or migration issue. Thank you so much for your understanding.
