RuntimeError: Lattice converged to a = 1.1955919831378603 Angstroms and c = 5.08473577535474 Angstroms (c/a = 4.252902), which means the distance between an atom and its nearest neighbor in an adjacent layer is 2.6344097137070888 Angstroms.  The model cutoff computed was 2.09999999832366 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
