Already running 10.1.8. Deleted it and reinstalled it as well. Problem persisted. I just deleted the preferences and attempted to export the file and it seems to work for now

Tried this as well. Machine crashed again while attempting to export

Using Nikon. Switched to a new memory card and reformatted it as well. Originally thought it might be corrupted files.
