When importing an FBX that has a material with a name that contains a slash (“/”) the editor crashes.
This can be triggered by switching to the “materials” tab on the import dialogue, or, when going through the import process a crash will happen at the very end.
It is due to the import folder creation process attempting to create a directory such as “/Game/ImportFolder//Material”
