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-extensions to 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.
