Migrating Echo Character from VOTA

I am trying to migrate the Echo character form the The Valley of The Ancient project so that I can take a look under the hood (mainly about IK etc). However once migrated to a new, clean TPS project if I try to add the character BP to a level, I can’t and if I try to open the ‘Echo_AnimBP’ i get a message saying “The Anim Blueprint could not be loaded because it is corrupt.”. This happens no matter what I do.
