Hi, I have used Photoshop almost since right from the start, but I have never encountered anything like my current problem before.
Recently, I wanted to do a sky replacement. Had an appropriate file open and clicked on sky replacement, panel opened, clicked on a sky and then the spinning wheel simply never stopped. Even went shopping, when I returned the wheel was still spinning, the app was not responsive any longer. Had to end process with task manager. Restarted PC (Windows 10, current version), opened PS, opened a file, small image, the PS background showed through! Brush tool, didn't work, etc. New layer, oh, the brush strokes I had made suddenly appeared. Now type tool. I could do what I wanted to and waited also a long time after entering text. Nothing. By now, the whole app was not responsive any longer. I went through similar procedures many times.
Next round, I get the following message after trying to open a second file
I clicked on Learn how to fix and the odyssey started. Reading page after page after page etc and trying many of the suggestions on all the Adobe Photoshop pages, starting with "Program error while opening files" Tried the rest of the web, nada, nada, nada.
I have no more hair left on my head, and Photoshop is still not working! Please, someone get me out of my misery. I'd like to work on my own computer again.
