Hmm, yeah, it might be a problem with Wyrebash, do you know if there's a way to install Enderal SE manually via the Skyrim SE steam game files?

a) You have an option to use the web installer, which will do everything for you.
b) If you are ready to resort to manual installation, what prevents you from using MO2?
c) For manual installation, unpack the archive into Data and run the game with enabled Enderal - Forgotten Stories.esm.
