   Thanks for your reply.

   Unfortunately, the latest version of Bun still doesn't seem to fix this. I bundled the latest OpenCode repo on Linux using Bun 1.3.8, ran the same steps from the other issue on Windows, and got the exact same error with a nearly identical stack trace.

   Sorry for the continued trouble, but it looks like upgrading the version isn't the solution here.

   Bun v1.3.8 ([`b64edcb`](<https://github.com/oven-sh/bun/tree/b64edcb490b486fb8af90cb2cb2dc51590453064>)) on windows x86_64 [AutoCommand]
