🐛 BUG: UnknownCompilerError: r.transform is undefined when building Astro project

[Sentiax]

What version of @astrojs/compiler are you using?

2.12.2

What package manager are you using?

bun

What operating system are you using?

Windows

Describe the Bug

Astro throws an UnknownCompilerError with the following stack trace when attempting to build or run the project. This happens consistently and seems to originate from the Astro compiler:

TypeError: undefined is not an object (evaluating 'r.transform')
    at <anonymous> (node_modules\@astrojs\compiler\dist\node\index.js:1:828)
    at new Promise (native)
    at transform (node_modules\@astrojs\compiler\dist\node\index.js:1:810)
    at processTicksAndRejections (node:internal/process/task_queues:96:5)

This error appears even when using the latest versions of Astro and compatible Node versions. It happens in a fresh project and appears unrelated to specific user code.

Bun's devs consider it an issue when a package works with Node but fails with Bun, so I recommend reporting this problem directly to the Bun repository.

+1 with 2.12.2 compiler under Bun. I am not sure if this is exclusively a Bun issue or if this happens with Node or other runtimes
