Handstake Failed & Data loss in the app

Today while working with IDLE I encountered a very long response from claude-3.7-sonnet-thinking, agent mode.
I thought the problem was in my PC, rebooted and after rebooting I saw that authentication in desktop cursor was gone.
When I logged in again I saw that all my past chats, also all documentation added to docs were gone.
Question - is there any way to get this back? Or do you have some technical works and everything will come back when they are finished?

P.s. Also now desktop cursor actually does not work, it takes a long time to respond to requests to claude-3.7-sonnet-thinking, agent mode

Hey, unfortunately, we are currently facing some issues with codebase indexing, which may cause the Handshake Failed error, and some degraded performance in the features that rely on it.

We hope to have those solved soon, but you can track the status of this on status.cursor.com

Apologies for any inconvenience this may cause!
