I am also experiencing a similar issue.
Whenever I try to delete features from an attribute table of a feature class or shapefile, ArcGIS Pro freezes indefinitely. It freezes as well if I use the "Delete" on the ribbon as well. However, the "Delete Features" geoprocessing tool works normally.
I have tried running the delete via attribute table in a different blank map, and the freezing behavior continues. I have tried running the delete via attribute table on a shapefile, behavior continues.
These files were hosted on my computer. Same behavior occurs if I attempt to delete from a layer located off my local drive.
Delete via attribute table works fine in ArcMap.
Creating a feature does not freeze the map.
I have restarted my computer. Closed and reopened ArcGIS Pro.
Any ideas folks? I have a suspicion that my ArcGIS Pro may be corrupted but idk.
