Error - ' unrecognised function or model ' when tried to run bertool Monte Carlo Simulation

I am using the trial version 2021a. I created a Simulink model with BPSK mod and demod and AWGN channel, to find the bit error rate using Error Rate Calculation. A Toworkspace block is also attached. When I try to plot my model (selected the model with its path) from Monte Carlo simulation using bertool, getting the error ' unrecognised function or model - mymodelname'. But example models provided by Simulink works. How do I link my Simulink model to Monte Carlo simulation?

try to type in command window

>>addpath ('your folder path which contain your .slx/.mdl') and press enter

should be fine when you run your monte carlo again
