It seems that on Windows, the LSP tool installed with npm's bun uses native bun to install, and the LSP tool opencode installed with npm's bun will crash when called, as if there is a compatibility problem

看起来在Windows上，安装的npm bun的LSP工具使用原生Bun，而安装在npm bun中的LSP工具opencode在调用时会崩溃，好像存在兼容性问题

Try it with a native bun
