"Constant" Error when loading in model using loadLearnerForCoder()

On a project at work, we are trying to convert a ML model to C++ using the MATLAB coder. We have done it sucessfully before but now something has gone wrong. In MATLAB Coder, when it runs the error check, it complains the function call for loadLearnerForCoder fails b/c "The Model must be a compiler-time constant". For the sake of a testing, I regenerated a smaller model (b/c our last one took a whole day to generate). When I load it in the same way, it gives no errors. When comparing the two models in MATLAB I can't really see an issue. Does anyone know how to debug this better or see what MATLAB is erroring out on? Also I cannot provide any code for this due to work. I've tried using coder.constant() and it doesn't work. I also used coder.screener() and it reported no problems.
