Hey, this is a known issue with ERROR_EXTENSION_HOST_TIMEOUT. We’re tracking it, but I can’t share an ETA for a fix yet. Main thread: Agent Execution Time Out
To understand your specific case, please share:
- Your exact Cursor version from Help > About, not latest
- The Request ID from the error right top of the chat > Copy Request ID
- Does this happen in any workspace or only a specific one? Is the folder empty or new?
- Are you using Remote SSH, WSL, or Dev Containers?
Workarounds that help some users:
- Reload Window via
Ctrl+Shift+P> Developer: Reload Window - Launch with
--disable-extensionsto check if a heavy extension is blocking the extension host - If the folder is new, try opening an existing project with code
If we have an update on the fix, we’ll post it in the megathread.
