Recorbox sometimes crashes when I select files and add them to a playlist. I cannot reproduce the problem, when I try again there is sometimes no issue at all, or it might randomly crash again. All files have been checked for errors. Since it happens quite often, this is quite annoying. Any idea where this could come from?
