My file after pasting an image turned white when putting the command "ctrl + z" to go back and after that nothing was seen anymore, and in "version history " is not even in the backup that is supposed to be saved, there is nothing , what do I do ? and also many layers were created
Maybe you hit a hot key that enabled an action or the action is set to CTRL V. Did you download any graphic style that runs actions to create art. The reason am suspecting this is a see a rotated artboard, you have extra layers created. You would have to maybe do many undos or go farther back in history if you have enough states set.
Do not think is in outline view as would see previews in the layers panel.
