Confusing error message when deploying Simulink model containing Stateflow charts

We have a Simulink model that we deploy to a TI C2000 processor that contains some Stateflow charts. For the most part, this works as expected, but on one particular laptop we get the following error when we try to deploy a Simulink model that contains any Stateflow chart at all. Deploying a model with no Stateflow charts works as expected. Has anyone seen this error before? We're completely at a loss and not sure how to further debug this.
CGIR assertion 'In mexFunction: at least one input argument is not a string.' failed in 'B:\matlab\toolbox\stateflow\src\sf_private_mexs\strrows.cpp:50'

Hi @Evelyn,
It appears that this issue is occurring exclusively on one particular system and involves a custom model rather than a shipped one. To address this, please follow these steps:
  1. Ensure that the correct TLC file, ert.tlc, is selected.
  2. Regenerate the code after deleting all build folders, such as slprj and rtw_ert.
These actions should help resolve the issue.
