Then, what you see, is only the empty default file. When there is an error with reading the file, no layers are the expected result.

What comes to my mind, that it is just an issue with the file format selection. Maybe the crash changed the config file, but not the drawing.
When you open the file, please check the selected file format in the drop down of the open dialog.
