"Sorry, something went wrong." When running Thread on Azure OpenAI

I get this error when trying to create Runs on a Thread

"last_error": {
    "code": "server_error",
    "message": "Sorry, something went wrong."
  },

Here is the full Thread config: (IDs removed)

Others seem to have had issues when using tools but you can see here that I've stripped all that out and am still getting the same error. The issue is not intermittent, it happens every time. What else could cause this error?
