Unexpected error on windows10 when running pkl-go-examples

[zerist]

go version go1.22.5 windows/amd64
Pkl 0.26.3 (Windows 10.0, native)
pkl-gen-go 0.8.0

foo.pkl
foo: String = "hello" bar: Int = 5

main.go
`package main

import (
"context"
"fmt"

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

)

type MyConfig struct {
Foo string pkl:"foo"
Bar int pkl:"bar"
}

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

Just run it, then I got
`[Running] go run "d:\backup\pkl-go-examples\pkl-go-examples\main.go"
panic: org.pkl.core.PklBugException: An unexpected error has occurred. Would you mind filing a bug report?

goroutine 1 [running]:
main.main()
d:/backup/pkl-go-examples/pkl-go-examples/main.go:23 +0x1db
exit status 2

[Done] exited with code=1 in 3.145 seconds
`
How can fix it? Or how can I report this error?
