Originally got this game on Steam but when I heard that there was gonna be a current gen update, I double-dipped on the GOG version to preserve my modded experience. However, upon trying to transfer all of my mods from Steam to GOG, the game just kept constantly crashing and I've already tried Archost's suggestion of editing fallout.ini to add the requisite lines to [ARCHIVE] Can't seem to find information on the crashes on GOG either since most people own the game on Steam, so I can only assume that the GOG version simply cannot be modded. To those wanting to get back into FO4, the most I can tell you is to stick with the Steam version and enjoy your mods while you can before the anniversary update inevitably breaks them.
