ArcGIS Pro 2.5 & 2.6 crashes when I try to start the application. It doesn't even make it to the splash screen. I've tried uninstalling and reinstalling with no success. When the problem started I was using 2.6 but reverted back to 2.5 and still experienced the same problem. I've attached my error report file (DMP file). The application worked fine the prior day.
I've got it working again. Followed the steps on this page (Clean uninstall of ArcGIS Pro - Esri BeLux ) for a clean install. Deleted some Esri system folders and changed a couple of registry values.
