Last week I upgraded from 10.3. to 10.6.1 and since then have experienced continual crashes while trying to edit a file geodatabase feature class using ArcGIS Desktop. The cashes occur at seeming random times and were varying in frequency from one every 25 minutes to one every 30 seconds. Today it escalated to one every 10 seconds. My editing consists of pretty simple cutting or merging polygons or adding data to the attribute table. It doesn't usually crash mid edit (as if it couldn't process) but happens after I've made an edit or after I've saved the file.
I have tried MXD Doctor (no problems found), creating a new copy of the feature class, checking specs of my computer to make sure it can handle 10.6 (all good), and considered upgrading the status of the Geodatabase but that option is not available because "This 10 Geodatabase matches the ArcGIS release you are currently using."
Any suggestions? Please!
