I could be working on a project for a while, between two maps and having no trouble modifying features. Then suddenly I will try to adjust the vertices on a line, and I get an error message:
modify vertices failed
Then, I can't seem to modify any features! I've tried restarting the program, and my computer. Has anyone else encountered this before? I have tried scouring the forums but couldn't find any other reports of this error. I'm working in ArcGIS Pro 2.3.0 on Windows 10. Here's a screen shot of my error and the image of the feature in my project that I am trying to modify.
