Need help troubleshooting error with Simulink Arduino tutorial related to time-response identification of RC circuit.

1 view (last 30 days)
I'm working on control systems tutorials found here. I've gone through the majority of the tutorial without issue, however if I try to run the both blocks highlighted, I get a very strange error (attached). If I run either the orange highlighted block, or the blue highlight block by itself, I have no errors, and get the expected output. It's just both together that I'm having issues with.
Does anyone have experience with this? If so, how can I fix the problem?

Try to build your Simulink model by using one of the following solvers instead of the default "ode3 (Bogacki-Shampine)" solver -
1. ode8 (Dormand-Prince RK8(7))
2. ode5 (Dormand-Prince)
3. ode2 (Heun)
4. ode1 (Euler)
This should fix the issue. You can change the solver by opening the Configuration Parameters (Ctrl+E) and then changing the 'Solver' under the 'Solver options' menu.
