3 problems have popped up in 26.2.0: No tool bar icons, can't select fonts with type tool, error code when exiting. Tool bar is just a bunch of dots.  Only type tool font avainable is Tahoma - get 

"Could not complete your request because LoadDeepFontCache in GetDeepFontCache failed" error code when trying to choose any other font. When exiting PS, get error code "Can’t write new document presets file"  Been using PS since Ver 7. Been using 26.2.0 since it came out. Uninstalled and reinstalled through Creative Cloud. Tried everything suggested on the web. Windows 10. Looks like I've got to dump PS and start looking at Capture One et al.
