Hi Martin,

i have reached out to the technical support but seems like they have not figure it out what is the problem right now .However, I have an older version R2020b which prompted me to install UE4.23 to make it compatible to run the supprot package in the older version. It is running smoothly now .

You may try the method above while waiting for the mathworks team to sorted it out for the issue occur in the latest version. Just a heads up it cannot open the newer version model but you can export it to a copy which support any version specified within R2022a.

There was an issue in R2022a with the "Vehicle Dynamics Blockset Interface for Unreal Engine 4 Projects support package" that contains the plugins required for co-simulation. The issue was fixed in R2022a Update 1.

You can upgrade the support package by clicking on "Add-Ons" in the MATLAB Toolstrip (the toolbar at the top of the MATLAB Desktop window) and selecting "Manage Add-Ons". Click on the "Updates" tab and then select the support package and click "Update".
