[BUG] GitHub connector shows "Connected" but exposes no tools in Cowork (Windows 11, app v1.8555.2.0)

What's Wrong?

Since yesterday morning, my GitHub connector no longer works in Cowork (the Claude desktop app on Windows 11). It still shows as "Connected" in Customize > Connectors, but it exposes zero GitHub tools in any Cowork window or session — Claude has no GitHub tools available at all, and searching the connector/tool registry for "github" returns nothing. Gmail and Spotify connectors keep working in the same sessions, so this is specific to GitHub.

This is account-wide: it happens in every Cowork window and has persisted across every restart.

Likely trigger: first thing yesterday morning the app forced me to update twice, back-to-back (two separate updates in a row). Right after, I had to pass three "prove you're not a bot" checks to get back in, and then Claude in the window incorrectly told me I was not online when I in fact was. GitHub has not loaded in Cowork since. A brand-new window today also surfaced a Google Drive connector I have never connected.

Note: this is the Claude desktop app / Cowork, not the Claude Code CLI. Desktop app version 1.8555.2.0.

Similar already-filed reports in this repo: issues 23775, 29415, 58172.

What Should Happen?

The GitHub connector should load its tools automatically in every Cowork session — as it did every day until yesterday. I have never had to manually re-add or "preload" connectors. Claude should be able to access my private GitHub repo (list repos, read files, commits, branches, etc.) the way it always has.

Error Messages/Logs

Steps to Reproduce

1. On the Claude desktop app (Cowork) on Windows 11, with the GitHub connector showing "Connected" in Customize > Connectors.
2. 2. Open a Cowork window / start a new session.
3. 3. Ask Claude to use GitHub, or check the available tools.
4. 4. Result: there are no GitHub tools available at all; a search of the connector/tool registry for "github" returns nothing.
5. 5. Gmail and Spotify tools ARE present in the same session, so connectors load in general — only GitHub is missing.

What preceded it: two back-to-back forced app updates yesterday morning, then three "prove you're not a bot" checks, then a false "you are not online" message. Updating again today to v1.8555.2.0 did not fix it.

Already tried, none restored GitHub: relaunch; multiple new windows; full quit of all processes then reopen; sign out and back in; disconnect and reconnect the GitHub connector.
