I am unable to place an image in Photoshop CC 2018 (most recent update). I end up with an error message about how the scratch disks are full. I only have one scratch disk and when in preferences I can't deselect the disk. I've purged all my data, reset preferences, I tried deleting temp files (although I couldn't find any), I tried clearing even more space on my mac, and disk preferences don't give me any options other the Macintosh HD and startup which both give the error message. The only thing I haven't tried is defragging the hard drive. I have the most recent OSX update on my mac. Is there anything I can do to fix this?
