Reality Converter: Conversion Failed: Validation fail on (good) usdz file

I have a usdz file that is viewable by quicklook and by preview, and also by my iPhone, but Reality Converter on my Macbook Pro Macos 11.6 fails to load it saying: Conversion failed: validation failed. What is wrong?

Hi, could you share the file with us? Also, could you try using the most recent version of Reality Converter? developer.apple.com/download
