What's Wrong?

I haven't found a different place to add my concerns. I'm using co-work with the desktop app on Mac. After upgrading to Claude 1.8555.2 (a476c3) 2026-05-22T23:04:37.000Z on mac os 15.7.4 it crashes constantly. I have depended a project on this workflow, and find no way to get any useful help. I would like to downgrade to a working version, but have understood that it is not possible. This means the project is stopping, and I'm asking myself, is this really a tool made for business, or just to play around.

What Should Happen?

There should be a way to get proper support
