I also have problems with a computer freeze when I'm deleting features in my geodatabase feature class. I had the problem with not being able to opening an Excel directly into ArcGIS Pro too (issue with the drivers; geoprocessing loading Excel does work). I've copied the feature class in a new fgdb, created a new feature class with the old one as template, even created a feature class completely from scratch in a completely new, local aprx. In the last one I drew a line, saved. Then wanted to delete it. ArcGIS Pro froze again. So I'm starting to think it has nothing to do with the dataset itself. I'm working with ArcGIS Pro 3.1.2.
