Photoshop becomes unresponsive when opening any previous file after Mac OS update and CC updates.

Friday, I went ahead and updated my Mac OS because all of Adobe programs were suffering crashes and slowness. When I returned to work on Monday, Photoshop would freeze upon opening any files. However, I can create a new project without it freezing but when I attempt to place an image from before it promptly freezes again. After searching various forums for similar problems, I did almost every suggestion I could find to fix the problem. I updated to the latest versions on Creative Cloud, un-installed & re-installed, re-installed my MacOS, checked my scratch disks, increased performance in PS preferences, checked the GPU, looked for wonky plug-ins etc. I'm simply at a loss here and am losing crucial work days. Any help is greatly appreciated. Thanks!
