This issue might be a duplicate of existing issues. Please check:

  • #7318: TypeScript LSP crashes with Bun segmentation fault on Windows 11 (similar Bun segmentation fault on Windows with AVX/CPU issues)
  • #3267: auto update causes: Bun segmentation fault (Windows) (similar Bun segmentation fault on Windows, crash on startup)
  • #6694: Bun crashes when OC subagent tries to invoke subagent (Bun crashes on Windows with segmentation fault)
  • #5901: Bun crash in the middle of a response (Bun crashes on Windows)

Feel free to ignore if none of these address your specific case.
