What's Wrong?

When I'm in Claude Code Desktop, I don't have the sidebar displayed.
It doesn't show me the session history there. I can't work on cowork or chat.

What Should Happen?

Shown in the picture.
As you can see, you can't click on the button that opens the sidebar because it's on the close button.
