Move Pawn in Mixed Reality (is stuck and failed to move)

Does anyone know how to make the pawn move? The pawn has been generated, but the pawn cannot move I looked at the MRUK Sample but it didn't work. If anyone knows how to do it, please give me some advice, thank you.  This is the output log of one of them.
