I'm having serious issues with PE 2018 (actually on a friend's PC which I installed for him). Everything works fine until I add an mp3 (tried many different ones, longer, shorter). When I apply a couple of simple changes after that (i.e. cutting out a scene, changing volume, adding transition effect), PE freezes.
Crash files are generated after each crash. They look like this (I only post first 20 or so lines, files are actually larger than 100 Kb):
