It ran for me (albeit so slowly I gave up after ~2mS), with "skip initial operating point solution" checked. At what sim stage did you get the error message?
usually if LTSpice has trouble establishing a stable operating point (errors are usually "time step too small, singularity matrix node(node-name)", or veeeeeery slooooow operation, it's because there's something causing the circuit to be unstable, such as positive feedback connected somewhere that expects negative feedback.
