I created a new project and recreated the character and animation blueprint and then tried to migrate those blueprints to another new project but I still get this error “Blueprint could not be loaded because it derives from an invalid class. Check to make sure the parent class for this blueprint hasn’t been removed! Do you want to continue (it can crash the editor)?” for the character blueprint. If I click “Yes” after this error shows up, the blueprint opens and now none of the nodes are visible and I’m left with a blank screen when on the event graph.
