my arcgis keeps showing a blank screen every time I open a new map project. my arcgis is up to date and my laptop is a windows 10 pro. I tried clearing up some storage space on my windows 10 pro by pressing the windows key and the R key, which opens the run tab. I then typed in %temp% and deleted most of the files in the folder that popped up. Then going to the recycle bin to completely erase those files for extra storage. Now my arcgis won't display a map. I tried using different imagery, but it still won't display. It shows a blank white screen for new and old projects. Help!
