   • TypeScript LSP crashes with Bun segmentation fault on Windows 11 #7318: TypeScript LSP crashes with Bun segmentation fault on Windows 11 - Same root cause (Bun v1.3.5 segmentation fault)
   • Segmentation fault (0xFFFFFFFFFFFFFFFF) in Bun 1.3.5 during Planner execution on Windows #11339: Segmentation fault (0xFFFFFFFFFFFFFFFF) in Bun 1.3.5 during Planner execution on Windows - Related Bun 1.3.5 crash on Windows
   • Suggestion to Update the BUILT-IN BUN VERSION in the Binary Package to Fix OpenCode Issues Caused by Bun bugs #11404: Suggestion to Update the BUILT-IN BUN VERSION in the Binary Package to Fix OpenCode Issues Caused by Bun bugs - Addresses the same Bun version upgrade need

   All these issues stem from the known Bun v1.3.5 segmentation fault bug on Windows. The recommended solutions are consistent: upgrade to Bun v1.3.6 or later, or use WSL.

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