Linearization error "Cannot resolve: [blockname]"

Good evening,

I'm currently having a problem with Model linearizer toolbox in Simulink.

My model simulates the motion of a Tractor-Semitrailer vehicle given a certain steering wheel input. Simply put, the goal is to try to implement different control strategies which minimize certain outputs. The configuration is that of a simple feedback block diagram:

ref |--------------| input |-----------|

--->o--->| Controller |---------->| Vehicle |--------|

^ |--------------| |-----------| |

| output |

|----------------------------------------------------|

I'm trying to implement an Adaptive MPC by means of the built in Simulink block, Therefore I need to linearize the "Vehicle" block at certain timesteps. I'd like to do so using the model linearizer toolbox, but whenever I try to run it the Diagnostic viewer pops up and reads out as follows:

The funny thing is that when I tried to run the whole nonlinear model with other control strategies the code and block diagram worked a treat.

Has anybody ever encountered a similar problem?

Thank you in advance for your help!

What happens if you use the linearization advisor as described here?

Troubleshoot Linearization Results at Command Line - MATLAB & Simulink (mathworks.com)

Does the "Model Linearizer" app open and then a later operation causes the diagnostic error?

Something with the name "Vehicle" is in the error message, but it isn't clarified what. If you can figure out if this is a function, variable, library link, ... then you will be closer to figuring out the source of the issue.
