What's Wrong?

I have a Claude Pro account, when I opened the Claude desktop app on my Windows 11 PC, I discovered the Claude Cowork tabs have disappeared. I am the administrator of my device, its updated to the latest version.

The previous Cowork conversations are also nowhere to be found in the sidebar.
