You’ll either need to comb through everything you did, or start over and rigorously test along the way.
AnimGraphs are unforgiving because they function off of a tick, so ANY mistake in your order of operations will show up immediately and often. There’s no hiding.
You should follow a tutorial and try again. You didn’t set up your cached poses correctly, and your code is NOT simple, so the fact that you haven’t fully mastered AnimGraphs yet means you almost certainly need to start over.
