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!!!
