Why are you switching from Idle to Walk if you have a blend space? If you are using the blend space you probably need to give it the movement speed of your character which you don’t seem to have in the AnimationBP.
To test, just make a float in your BP and drag the blend space into a state. Plug the float into the blend space and manually move the float up and down.
If the raw run animation file is not working then you need to test with different export and import settings.
