I imported a CAD drawing into PRO version 3.0.2, started cleaning it up, then started tracing polygons over the polylines so I could have my own polygon layer to stylize and make pretty for them. This morning when I come into work I cannot open this file. I can open every other project that I have worked on, but for some reason not this one. It is giving me a warning saying "Opening the selected ArcGIS project failed. This project was saved using a newer version of ArcGIS PRO : ."</P><P>That doesn't make any sense to me because I literally worked on this yesterday and now I cannot access it. Nothing has changed in our department, and nothing needs updating.</P> Wed, 05 Oct 2022 15:51:13 GMT https://community.esri.com/t5/arcgis-pro-questions/failed-to-open-project/m-p/1219006#M60717 MattBlades 2022-10-05T15:51:13Z https://community.esri.com/t5/arcgis-pro-questions/failed-to-open-project/m-p/1219154#M60735 <P>Hey Matt,</P><P>I am not sure if this will help or not but there could be a couple of drivers you could install to see if it allows you to open your project.
