What's Wrong?

When I start the app the tabs for Chat, Cowork and Code. The app is. functioning, it is in chat mode, but I cannot switch to the other modes.
Both Cowork and Code seem to be available in the settings.
I am on a Pro plan.
I restarted the app this morning and it performed an auto update. This may have caused the issue. Yesterday the tabs were still available.
Claude app version 1.2581.0
MacOs Sequoia 15.7.4
MacMini M2Pro

What Should Happen?

Tabs should be available. There is no way to use Cowork now.

I have the same issue. Cowork tab dissapeared over a week ago, and I've updated multiple times. Claude itself is useless to fix the issue. At this point, I'm not feeling I'm getting my $ worth out of the account. Any suggestions?
