Can you please add a break point to C:/Users/Eric/go/pkg/mod/github.com/go-text/typesetting@v0.1.0/fontscan/scandir.go:38 to find out what font is being loaded and report that here (uploading if possible)? All we can tell from the error stack is that a font on your computer is causing a crash when it loads...
