We have ArcGIS Desktop 10.6.1 and it crashes whenever we open ArcMap or ArcCatalog. Sometimes we are able to use it for sometime and sometimes it crashes instantly. The crash is not dependent on any tool or any specific activity. Even if ArcMap or ArcCatalog is idle, after sometime it crashes and this window appears.
