The patch is for Data Reviewer (extension of ArcGIS). I don't think updating the patch would help.
At what point in the model's workflow, does it crash?
Ensure that the data path of both inputs and outputs are short (< 255 characters , i.e., path + filename), and don't have special characters and spaces (except underscore).
It would be wise to contact the Esri Tech Support. They can work closely with you to resolve the issue.
