Analysis of Cursor IDE Crash

Exception Code: 0xc0000409 - Stack Buffer Overrun

This error is significant and explains your Cursor IDE crashes:

  • Exception code 0xc0000409 = “STATUS_STACK_BUFFER_OVERRUN”
  • This is a serious memory safety violation where the program tried to write beyond allocated memory
  • Windows detected this violation and forcibly terminated the process

What’s Happening

The crash is occurring in inno_updater.exe, which is Cursor’s automatic update component. This suggests:

  1. The application isn’t crashing randomly - it’s crashing during update checks
  2. The updater has a buffer overflow bug (a security vulnerability)
  3. When the updater crashes, it may be taking down the main Cursor application with it

Solutions to Try

  1. Disable Auto-Updates (if possible in Cursor settings)
  2. Contact Cursor Support
  • This is a legitimate bug they should fix
  • Share the error details with them
  1. Try Manual Updates Only
  • Update Cursor manually instead of relying on the auto-updater
  1. Check for a Newer Version
  • The current version has a significant bug
  • A newer version might have fixed this issue

This explains your frequent crashes and is definitely a bug in the application rather than an issue with your system.
