panic trying to load Vite.createServer()

Getting a panic trying to use RunAsync to import and invoke a JS method from a C# app using EmbeddingThreadRuntime/etc.

This is using the main branch as of today. The libnode itself was built by me.

The problem is specifically limited to Vite.createServer right now. I can't figure out what it does internally to cause this. But my suspicion, thought I can't yet prove it, is that it loads a module which loads a module which loads a native module, which fails. Since I don't understand what's happening enough I haven't been able to create a reproduction.

Some enlightenment about what to look at may be useful. Is this a crash on the node side, because it's doing something truly awful, or is it some interaction with NodeAPI?
