What's Wrong?

This relates specifically to Claude Desktop App Chat (not Claude Code)

Several projects are missing from "Project" tile view dashboard.
When I search for these projects from the "Projects" dashboard, they CANNOT be found
When I search using global search using magnifying glass just above the sidebar, they CAN be found (individual chats and whole projects)
Once found using global search I can dive inside each and it appears they are all intact (just don't show, cannot be found and are not registered in the projects tile dashboard)
Once found I can pin them to side bar and access this way
When I open these "missing" projects I see the "back button" above is still labelled "<- All projects" and when clicked it takes me to projects tile dashboard but the project does not re-appear there.
This issue is persistent across multiple PCs running same version of Desktop App
This issues is not related to Web version. When accessing Claude via web, the projects are still listed in the Projects dashboard

What Should Happen?

I should be able to see all my projects in the dashboard view
