RuntimeError: Lattice converged to a = 2.0586711755887697 Angstroms and c = 4.72360709187736 Angstroms (c/a = 2.294493), which means the distance between an atom and its nearest neighbor in an adjacent layer is 2.644016829121026 Angstroms.  The model cutoff computed was 2.2999949739501244 Angstroms.  Since the smallest interlayer atom distance is greater than the model_cutoff, the minimization has converged to a state where there are no longer interlayer forces, indicating the lattice is unstable.
Command exited with non-zero status 1
