Hey, thanks for the detailed report and logs. This is a known crash pattern in the retrieval-always-local extension host on Windows. We’ve been seeing it from several users recently.
The crash code 0xC0000005 (Access Violation) points to a native crash in the local indexing binary crepectl, which gets triggered through cursor-retrieval.
Try this:
- Open Cursor Settings, not VS Code settings, then go to Indexing & Docs
- Turn off Codebase Indexing
- If you see Index Repositories for Instant Grep (BETA), turn that off too
- Restart Cursor
Another user found that the Instant Grep (BETA) option was the trigger, especially on larger projects: Extension host terminated unexpectedly always - #6 by facio313
You’ll lose local codebase search, but chat, agent, Cursor Tab completions, and everything else should work.
A couple questions to help narrow this down:
- How large is the project you’re opening, roughly how many files
- Do you have any VPN software installed on this machine, even if it’s not running? Another user found that removing VPN software fixed the crash completely: Extension host terminated unexpectedly no matter what i try - #9 by Brian_Walch
The team is aware of extension host crashes in this area. Your report and logs help with prioritization. Let me know how it goes.
