Does your NavLab pipeline fail when you select the Automatic dynamics model option?
Why does NavLab fail to process sometimes? This can be for several different reasons including, but not limited to, unideal vehicle dynamics, reference station data issues, etc. One method of troubleshooting is to select a dynamics model other than Automatic. The Automatic dynamics model attempts to process using the Airborne and Ground Vehicle options but does not attempt to use the Marine, Pedestrian, or UAV profile. If the flight in question was flown slower than normal (less than 5 m/s on average), try using the Pedestrian dynamic model.
