What's Wrong?

I have a Claude Pro account, but yesterday when I opened the Claude desktop app on my PC, I discovered the Claude CoWork and Claude Code tabs have disappeared. They no longer appear at the top of the app as they used to, and they are also nowhere to be found in the sidebar. Along with the options to use Code and CoWork, all of my previous conversations that took place in CoWork (I haven't used Code) are gone.

Here are steps I've taken to troubleshoot:

Restarted the app from scratch - No change
Removed the app using add/remove programs and re-downloaded and installed it from scratch - No change
Rebooted my PC - No change
Checked my Pro account status to make sure there were no missed payments or anything that would inactivate it - Last payment was 14 days ago (I'm on the monthly plan) and it processed successfully

What Should Happen?

I should regain access to Code and CoWork and my previous CoWork Conversations should be restored

None
