This is a routine that comes with matlab. I have successfully run it in matlab2016b and matlab2019b, but I can’t succeed in matlab2021b. I’m not sure what caused it.This routine is ‘Add, Build, and Remove Objects in Gazebo’

Hello,

This may seem like an obvious question, but I want to cover the basics first. Did you get the new VM as directed by this example? ROS Toolbox is using Melodic for communication since R2020b, so if you're using the same VM as you did with R2019b, there may be issues communicating.

Since that seems to have resolved the issue, copying my comment into an answer:

Make sure to get a new VM as directed by this example any time you upgrade your release. ROS Toolbox is using Melodic for communication R2020b-R2022a, so if you're using the same VM as you did with R2019b (or before), there may be issues communicating.
