I am having issues with editing--or rather, deleting--points in Pro. Whether I open an existing project file, import a layer file either from my organization's online portal or from a newly packaged layer, and despite having no read-only or protective settings enabled, I get error messages when trying delete erroneous points. A pop-up window with the title "Delete Features" with a red x graphic and the text "Edit operation failed" appears, and the points do not get deleted. Attached is a screenshot.
My ArcGIS Pro version is 2.9.4, which is the most recent my organization allows.
I am accessing Pro on a Windows 10 Enterprise operating system (Dell Latitude 7410 laptop).
Any ideas on what I can do?
