I assume you are doing sometihng [like this](https://gitlab.kitware.com/physiology/unity/-/blob/master/Scripts/PulseEngineScenarioDriver.cs#L131)

I think Pulse is failing to [find the data files it needs from disk](https://gitlab.kitware.com/physiology/engine/-/wikis/how%20to%20connect%20to%20pulse#application-execution)

Try adding this line before your InitializeEngine call:

`scenario.GetPatientConfiguration().SetDataRootDir(Application.streamingAssetsPath+"/Data/");`

Those directories should be under that `Data` folder  
Hopefully Pulse will then be able to find the files its looking for
