Cannot see new image when open in Photoshop showing a black screen ?
Does a restart fix it? Does this happen to all new images when you open them now? I've seen that once or twice, but a restart solved the problem. It could be a graphics card issue, though. If a restart doesn't fix it, if you'll post more information, your OS, version of PS, graphic card info, and the image format affected by this, the Adobe team will be back at work Monday, if not popping in today, and they can help you troubleshoot.
I would suspect a graphics driver issue. Make sure your graphics driver is up to date directly from the card manufacturer's website. Instructions here: https://helpx.adobe.com/photoshop/kb/troubleshoot-gpu-graphics-card.html#Troubleshoot
