How to resolve step size?

https://www.youtube.com/watch?v=jQOOCD-EqqY&t=13sI was trying to make this same project on MATLAB. But I am getting errors.

An error occurred during simulation and the simulation was stopped

Caused by:

• Derivative of state 'DC_Motor_SpeedControl.DC_Motor_Subsystem.DC_Motor.i_L' in block 'DC_Motor_SpeedControl/DC Motor Subsystem/DC Motor' at time 1.96 is not finite. The simulation will be stopped. There may be a singularity in the solution. If not, try reducing the step size (either by reducing the fixed step size or by tightening the error tolerances)

You can download the MATLAB code directly:
