It appears that these are not the official thermal descriptions provided by the manufacturer on their website. We would recommend that you use those models if possible.
It is also not easy to fully diagnose the issue without having your circuit model that shows the error message. I suspect, however, the issue is a numerical one. For example, with the thermal description you attached for C2M0080170P, the Conduction Loss current axis has a value of 6.133300000000001e-15. You should change this to 0. Also, the datapoint at 25C and 10A is 0.8436100000000001. This should probably be truncated to 0.84361. Further, your thermal impedance coefficients have a complexity that may lead to a numerically stiff system.
Let me know if this helps.
