I edited a feature class in a File GDB using ArcGIS 10.2 (renamed a column in ArcCatalog, recalculated field values, etc), then I closed the mxd.
Then the mxd couldn't be opened ("ArcGIS Desktop has encountered a serious application error and is unable to continue").
And the feature class I edited couldn't be loaded and couldn't be double clicked ("ArcGIS Desktop has encountered a serious application error and is unable to continue").
There is only "copy" shown by right click the feature class (but nothing can be copied).
What to do to access this feature class?
