Welcome aboard. Enjoy the ride.
We look forward to seeing more posts and samples of your work.
Before we can help you with this, we need some more information.
What is a "newly Photoshop document?" Is it a new image downloaded directly from your camera? If so, which camera and is it a RAW or JPEG image. Or is it an image recently processed in Photoshop? If so, what format was it saved in?
What will it not open in? Directly in Windows 10, or in Photoshop (if so which version), or some other software?
Did everything work fine before the update and what kind of update was it? Was it an incremental update within Windows 10 or was it an update from a previous version of windows?
