I have been working on a project in ArcGIS Pro 2.1.2 and as of this morning have been unable to save my edits that I have made to data in a map (in map mode, not layout mode). I am able to make the edits, but when I go to save them I get the following error window:
If I try to make additional edits and save them after I receive this notification, the "Save Edits" button becomes grayed out like so:
I have tried to edit several different layers (ensuring that I am only editing one layer at a time), and each time I have received this error. I have also shut down and restarted the program several times and this problem is still occurring. I have even removed the map and added it back in to the project, and the error still occurs each time I try to make edits. This leads me to believe that it is an issue with the project itself, but I am not sure what kind of issue that would be. I have looked around to see if anyone else has had the problem, but have been unable to find any such forum post/Stack Exchange/etc.
The project uses an imported .mxd from ArcGIS 10.3 as the basis for its layout (which was imported when the project was created), and the map I am editing was created from one of the map frames in the layout mode. This is my first project for which I have used ArcGIS Pro (I have previously only used ArcGIS 10.3/10.4), so I apologize if any of my Arc GIS Pro terminology is inaccurate/confusing.
Any help that anyone could provide would be very much appreciated. I am also more than happy to provide any and all additional information that would be helpful.
