I'm facing an issue with ArcGIS 10.3. When I try to use symbology type "category" the program crashes. It seems that is not a matter of data because I used the data before and nothing happened. The problem started yesterday after a windows 10 update so I consider something relate do this update (may 10).
I tried the complete uninstall and reinstall and didn't solve the problem.
I tried also save the MXD with another name in other location.
So my question is related to the possibility of a problem caused by an windows update.
Any ideas?
