missing rekordbox xml files

RB is working fine, but I want to use RecK. And that needs to use the XML. And for some reason the XML doesn’t seem to exist when I look in the library folder

So I need to create one. And I think the best way is to export collection in XML format. Correct me if I’m wrong? Problem is that when I do it has twice got stuck at 5%. My collection is pretty big but not sure what the issue is. I use iTunes and keep folder organised by iTunes if that makes and difference.

When I press refresh of the xml in the rekordbox tree it says that the xml can’t be found or accessed or something like that. I don’t understand how RB is working properly without an XML
