An unexpected error has occurred

I'm trying to load a sample pkl file using the following code. I'm on go 1.24.2. I get back this error on Windows, but it succeeds on WSL. The versions are Pkl 0.28.1 (Linux 5.15.0-1064-aws, native) & Pkl 0.28.1 (Windows 10.0, native) & github.com/apple/pkl-go v0.10.0

go run main.go 
panic: org.pkl.core.PklBugException: An unexpected error has occurred. Would you mind filing a bug report?

Input: foo.pkl

keys {
    ["g"] {
        url = "https://google.com"
        keys {
            ["apple"] {
                url = "https://google.com/search?q=apple"
            }
        }
    }
}

Program: main.go

package main

import (
	"context"
	"fmt"

	"github.com/apple/pkl-go/pkl"
)

type Query struct {
	Url  *string            `pkl:"url"`
	Keys *map[string]*Query `pkl:"keys"`
}

type QueryConfig struct {
	Keys map[string]*Query `pkl:"keys"`
}

func main() {
	evaluator, err := pkl.NewEvaluator(context.Background(), pkl.PreconfiguredOptions)
	if err != nil {
		panic(err)
	}
	defer evaluator.Close()
	var cfg QueryConfig
	if err = evaluator.EvaluateModule(context.Background(), pkl.FileSource("foo.pkl"), &cfg); err != nil {
		panic(err)
	}
	fmt.Printf("Got module: %+v", cfg)
}

Encountered the same problem on Windows 11 24H2 with Pkl 0.28.2 (Windows 10.0, native) and it's working on WSL: Pkl 0.28.2 (Linux 6.8.0-1024-aws, native). Downgrade to Pkl 0.27.1 (Windows 10.0, native) - version present in tests - didn't help.

Looking at #73 and lack of Windows specific tests, I assume Windows might have some problems still.

At least some better error message would be nice to point where the error is.
