[TOTAL NOOB] Can't find out why Animation doesn't work

hello, this is my first post here and it starts quite embarrasing…

My problem is, I started the Tutorial ‘How to setup Character Movement with Blueprints’ and followed everything nice and tidy, at the end of the tutorial i was like “yeah now i can start this thing and everything will work!”

Well no, it doesn’t work. The walking Animation doesn’t work and nothing else does. This is the Error that comes up after quitting the Play Mode:

which leads to this:

which looks exactly like step 15 of this.

What did I do wrooooongggg :c

Thanks a bunch in advance!

Have your sorted your movement keys in the project settings?

Is your character in a T-pose, or is the idle animation being applied? (That will help work out where the problem is).

I haven’t really sorted them, I just blindly did what the Tutorial wanted me to do and I tried to figure out things on my own – thought I would understand it – and this is what happened… The character starts in a frozen standing pose. :frowning:

How do I sort my Movement Keys?
