You can try reinstalling the game, but once I "fixed" this crash by deleting a strangely named file without an extension called index in one of the game's folders. At least, the appearance of this file always caused an empty object column in the editor for me.
Indeed. I removed the file index.bin (unreadable) from the data folder, and it seems to be working now. May it bring you good fortune.
