Hey, thanks for the report with the request ID and stack trace. That really helps.

This is a known bug on our side. Cursor doesn’t handle the case where the OS reports the time zone as Etc/Unknown correctly. Instead of falling back to UTC, it crashes.

Temporary workaround: make sure your time zone is set correctly in Windows:

  • Settings > Time & Language > Date & Time
  • Turn off Set time zone automatically
  • Select your time zone manually
  • Restart Cursor

The team is aware of the issue. Your report helps us prioritize it. Let me know if the workaround helped.

Thank you. I followed your instructions, restarted both my computer and Cursor, it works!!!

Hey @Alice_Patterson

Update: the server-side fix is deployed. The Invalid time zone specified: Etc/Unknown error in Chat/Agent should no longer happen, we’ve fixed the backend crash when the OS reports an invalid time zone. The workaround of manually setting the time zone in Windows is no longer needed, and you don’t need to restart or update Cursor.

If you’re still seeing the error, please start a new thread and include the Request ID and your Cursor version.
