Photoshop not rendering png files or copy/paste
Recently photoshop Version: 23.3.0 (on windows) stopped rendering png files or any thing I copy and pasted
When I try to copy and paste a file or screen shot it will show a very low res pixelated preview of the image in the navigator panel but the image itself is empty. If I save the file - it only saves a very low res version of the screenshot/image.
And while I can open .png files - again - they do not render on the screen - I just get the big white box (although again a low res version is in the navigator panel)
Any ideas on what has gone wrong and how I can fix this?
