Hi @huynh_ductrung

This is a known issue affecting the current stable releases. A fix has been identified and should ship in an upcoming update.

In the meantime, clicking the Reload Window button shown in the error dialog should recover the session. If it recurs frequently, disabling extensions you don’t actively use can also reduce the likelihood of timeouts.

Several other users have reported the same issue: Agent execution provider did not respond, Agent Execution Timed Out.

I updated and restarted the Cursor. It fixed the issue.
