What's Wrong?

The Cowork plugin marketplace shows blank/grey placeholder tiles
and never loads. Both "By Anthropic & Partners" and "Personal"
tabs are affected.

Tried: restarting app, checking internet connection, switching
to mobile hotspot. Nothing works.

This appears to be the same issue as #28853 — plugins.claude.ai
does not resolve via DNS on Windows.

App version: 1.1.6041.0
OS: Windows 11

What Should Happen?

The plugin marketplace should load and display all available
plugins in both tabs (By Anthropic & Partners and Personal)
