It looks like this is the same error as this GitHub issue, which has been fixed. It appears that your options are 1) switch from Autosize to a hardsized value for the AirLoopHVAC:UnitarySystem's Minimum Supply Air Temperature, or B) upgrade to a newer version of OpenStudio that supports EnergyPlus v9.3.0 or newer.
