If you somehow (like me) put in a wrong path the editor will crash everytime you open it, deleting and re-installing it from steam won't help as the editor apparently remembers your wrong settings.
I found a fix though, go to the editor folder.
C:\Program Files (x86)\Steam\steamapps\common\The Divinty Engine Enhanced Edition
Find the file named "config" open it and delete the 2 wrong path you've put in.
Next time you open the editor you will get a new chance to put in the correct paths.
