It appears that the Anim Instance class is no longer accessible. As a result, no animation blueprints made are accessible via blueprints - regardless of whether or not the skeletal mesh actually uses the BP, they're just not recognized. This is a regression from 4.22.3 (CL-7053642).

This was reported and tested in 4.23 (CL-7838574). This was reproduced in Main 4.24 (CL-7971874)

Steps to Reproduce
  1. Open the UE4 Editor and create a Third Person template project
  2. Open the ThirdPersonCharacter BP and try to cast to ThirdPerson_AnimBP

Results: No animation blueprint classes appear in the list.

Expected: Animation blueprints can be cast to
