Failed to open table Error creating map member

[mariorizario]

This is the second time I have run into this problem, and not sure what is going on.

I was editing polygons in an existing shapefile when I saved it it said something along the lines of "number of shapes do not match records" and a few of the polygons that I had created had disappeared.  I shut it down, and restarted ArcPro, and now the shapefiles won't load at all. Instead I get the following message:

Failed to open table.

Error:

Error creating map member.

This is the second time I have run into this problem. I originally thought it was because there were a lot of records within the shapefile (>20,000) so I clipped the shapefile to only include records I was editing. This seemed to work for a while until I got the message today.

Any ideas? This is the second time this has happened and each time I have lost about 3-4 days of work. My process seems to work fine until the 3-4 day.

Thanks Dan. I was able to copy the shapefiles into a local geodatabase, but none of the edits that I had previously made are there, only the original shapefile prior to edits is there. I'm assuming you mean next time I am completing edits to use a geodatabase as it is more stable?
