I am assuming you are using MATLAB R2020b or R2021a version. The error that you are facing is related to connection error during XCP external mode simulation due to DWARF parser internal error. This was identified in the external bug report that can be found here: https://in.mathworks.com/support/bugreports/details/2558824

You can try the workaround provided in the EBR. The issue has been fixed in MATLAB R2021b, so you can update your version accordingly if need arises.

Hope this helps.
