lowQualityThumbnail in QLThumbnailGenerator stops working from 15.2

Our code is using .lowQualityThumbnail to generate a thumbnail, it stops working when users update to 15.2 .

Test it with a regular jpg file for fileURL.

The only way to make it work is to change it to .thumnail or remove it.

It's not deprecated, is it a MacOS bug? customers don't want to keep updating the software.

Everything works in MacOS 15.1

import QuickLookThumbnailing

func generateThumbnail(for fileURL: URL, size: CGSize, scale: CGFloat) {
    let request = QLThumbnailGenerator.Request(fileAt: fileURL, size: size, scale: scale, representationTypes: .lowQualityThumbnail)
    
    QLThumbnailGenerator.shared.generateBestRepresentation(for: request) { thumbnail, error in
        if let error = error {
            print("Error generating thumbnail: \(error)")
        } else if let thumbnail = thumbnail {
            // Use the thumbnail
            let image = thumbnail.uiImage
            // Do something with the image
        }
    }
}
