Can someone explain how to resolve this issue?

Can you send builder-settings.json file?

It's in C:\Users\ADMIN\Documents\Vuforia Studio

@pawelek103  Hello actually based on the path you have given, I have checked the JSON file it was empty don't know why I guess when Microsoft edge auto-updated itself when vuforia studio is running this caused the JSON file to corrupt so I renamed the VuforiaStudio folder as a "backup" and downloaded it again through the same setup file and it worked. thanks for the hint!
