The stretching is from a wrong or missing skeleton file. Delete any skeleton files from Data\Meshes\Actors\Character\Character Assets\ Specifically skeleton.nif skeleton_faceBones.nif and skeleton_female_faceBones.nif Also, make sure that 'CaN - Player (Race) - Main.ba2' and 'CaN - Player (Race) - Textures.ba2' for your chosen race are inside your data folder. Some mod managers seem to have problems copying those.
