Valley of the Ancient - Hero Gets Stuck

I was looking at Valley of the Ancient as an example of how to integrate cutscenes/cinematics into the gameplay of my own UE game. When I play the demo, my hero character (the girl character) gets stuck knee deep in the terrain after she beats the big robot. Is anybody else getting this problem? As I say, I want to use cutscenes in my game, and would like to know what is causing this error and how to fix it. I am using an I9 13th gen CPU with an RTX 4090 GPU, 64G Memory, Windows 11.
