Has anyone had trouble opening a 2.9 project in 3.0 where shapefiles are the dataset? My Arc freezes with no error message when I try and I have to use task manager to close it. I have uninstalled and reinstalled ArcGIS Pro 3.0.0 and it still freezes.
It will run perfect with .gdb and feature services.
One thing to try is run the Repair Geometry GP tool in the Data Management->Features toolset on the shapefiles. "Maybe" ArcGIS Pro 3.0 "sees" an issue with the shapefile that 2.9 did not?!?
