Agent Execution Timed Out keeps appearing on a managed work laptop. Rephrasing the prompt and starting fresh chats changes nothing. What does the message indicate, and where should the investigation go?

The principle — The message is about startup, not about the request. Agent features live inside Cursor's extension host, and if that host has not finished starting within sixty seconds there is no agent available to run the prompt. The editor then reports a timeout that reads like a slow answer, which sends people back to their prompt instead of to their machine.

Why the key is correct — Cursor documents this error as the extension host failing to initialise in time, which puts the evidence on the local machine rather than in the conversation. The recommended move is to export the Main, Window and Extension Host logs and to inspect the Extension Host output panel, where an empty panel is itself a strong diagnostic signal. On managed or enterprise hardware, endpoint security software inspecting the host process is one known cause, and the remedy is process and path exclusions applied by the IT team.

Why the others are wrong — A rate limit announces itself in its own terms and eases with time, while this failure repeats at once and survives new chats. A corrupt index degrades file discovery for an agent that has already initialised, so it cannot explain an agent that never appeared. And blaming model speed misreads the error entirely, since no request was ever dispatched.

Remember this — Persistent agent timeouts on a managed laptop are a startup problem, so gather logs before touching prompts.
