BunInstallFailedError when upgrading opencode #4047

Description

I have been using opencode for quite some time now (and loving it!). When trying to upgrade to version 1.0.39 (and also just upgraded to 1.0.40), I get this error when opening opencode again. I also installed the opencode extension in my editor of choice zed.dev recently (which didn't seem to work). Maybe it's related, maybe not?

The error message I get from the zed.dev extension: Internal error: "server shut down unexpectedly"

The opencode help command and some others do seem to work, but trying the opencode auth login fails after selecting any provider.

I have already tried removing all opencode configuration and fully uninstalled all caches, as well as reinstalled using homebrew, npm and the curl script. All seem to give the same issue. I am on a base model MacBook Air M2 using Ghostty.

OpenCode version

1.0.40 (latest at time of writing).

Steps to reproduce

1. Install zed.dev opencode extension
2. Upgrade opencode to latest version
3. Unable to launch opencode.
