What Should Happen?

Tab should be on the right.

Yes, this is a known bug. Multiple users on similar Desktop versions are reporting Code and Cowork tabs disappearing after auto-updates. Reports include full uninstall and reinstall not fixing it -- only the Chat tab visible after auto-update. Quitting, relaunching, signing out and back in, and reinstalling all fail to restore the tabs. GitHubGitHub
You're hitting a variant of this. Cowork shows for you but Code doesn't.
Things to try, in order:

Quit fully and relaunch (Cmd+Q, not just close window)
Check ~/Library/Logs/Claude/main-window.log for preload script errors:

I use Claude Browser on EDGE and WINDOWS 11, i have installed the extension without problems, I click on the extension to bring it to the forefront. I open a new tab, I click on CLAUDE and appear a window on the left, where CLAUDE tells me to write what I want to do and he will do it for me... I write it, I see it starts to work... then I click on a tab already open to see of another thing I was doing.... But when I try to go back to the tab of Claude, i noted there is no more, disappeared entirely... I have tried to look for possible solutions but nothing... some idea?
