After looking into this further, I found another user that had a similar issue. If you still have access to the old laptop (or its drive), you can copy the profile folder over to the new machine and your history should appear. Detailed recovery steps were shared in this thread: I lost all my chats, context, etc after software update.
For panisant, since you mentioned your previous laptop “got ashed and never rebooted,” if the drive isn’t recoverable, unfortunately there’s no server-side copy to restore from. In that case I’d recommend opening an AWS Support case to confirm whether any recovery options exist on their end.
Hope this helps!
