The error statement: Error evaluating 'InitFcn' callback of block_diagram 'untitled'.
Callback string is 'RPInit
SimMechanicsRigidlyBoundBlock'
Caused by:
block_diagram does not have a parameter named 'SimMechanicsRigidlyBoundBlock'.
I followed this youtube video to get to know how to use the app and followed the exact steps given in the app because I am a begineer to MATLAB and SIMULINK.

This error occurs when you copy an environment form the library to a blank model. Here are two solutions:
  1. Click on the arrow in the lower left corner of the environment to look under the mask. (This should update the model properties). Then you can navigate back to the top level of the model.
  2. Start from a provided example instead of creating a model from scratch.

I recently ran into this error and figured I'd post a screenshot relating to your solution 1, in case any beginners need clarification. The arrow mentioned is circled in red.

Do you have a Simscape Multibody license? If you type in
>> ver
in MATLAB, does that toolbox show up?
