Where does the bug appear (feature/product)?

Grok Bot

Describe the Bug

One specific Grok Bot (MC Hub) stopped responding. Other bots on the same Agent Computer still work (MC Brigid is fine). The shared computer looks fine. This matches the stuck-runner reports.

Please restart ONLY this bot’s runner. Do NOT Reset / rebuild / Update the Agent Computer. Do NOT delete the bot. Conversation history must stay on the original bot.

Bot: MC Hub
Agent / conversation id: a1c94fa2-364d-4cdf-b1c1-d878cfff5a06

What I’m seeing:

Messages to Hub get no reply
Other bots on the same account still reply
Computer takeover / desktop still looks operable
Not treating this as a weekly usage limit (other bots work)
Already tried:

Short ping from another bot
In-app product feedback asking for a runner-only restart
Please clear the hung runner / queue for this bot only. Thanks.
