Hi there,

As Lightroom is not able to open some raw images, would you mind telling us which camera you're working with?
Also, what's the version of Lightroom and operating system you're on?

Could you try converting the raw files to dng and see if Lightroom opens them? https://helpx.adobe.com/in/photoshop/using/adobe-dng-converter.html
