What's Wrong?

After claude desktop performed an update today, the the upper middle menu bar (the bar that contained "chat" "cowork" and "code") is no longer present. I followed Claude's suggestions to resolve include uninstalling/reinstalling, but the problem persists. Degraded functionality.

What Should Happen?

After the update, the "chat" "cowork" and "code" menu should be present.
