Hi all I am running on a Umbraco 12 site hosted on IIS using model builder set to Auto and when I create a new document type with a template and then rebuild model builder in the settings menu I get this error in the log and my page is just error 500. I can see the generated model in the models folder but the page will not load. any help would be great I've been bashing my head on it for a while.

I have even tried deleting the generated model and then switching models builder to Manual and using the settings menu to rebuild, restarting the website on IIS, making sure the models folder has maximum permissions and still comes up with the same error.
