I was editing the table of a gdb feature class in ArcCatalog when I started getting the message "General function failure" in response to deleting a field.
I closed out and reopened and now the entire feature class has the red exclamation point, and when I try setting the data source, it gives me the error message "Error setting the data source. General function failure."
I've searched for the problem and it doesn't seem like this has been a thing since ArcGIS 8.x or is only a problem if you are trying to use a personal database from MS Access, which I am not.
What is going on?
