I have been running TWS API with Python for years without many issues. Suddenly my code that worked yesterday is no longer working. Any file I run, I get an error like this:

I am running Windows 10, TWS Latest, API Latest. About the time this error started, I had to switch from Visual Studio Code to Visual Studio Code Insiders. Python files run regularly under VS Code Insiders just fine.
What could cause this to happen?

Nope. The advancedOrderRejectJson field was introduced in API version 10.14.01 in January 2022 and went through beta and is, obviously, in the current "latest" version 10.17.01.
Version 10 has many and large changes compared with the current stable version 9.81 and is still rapidly getting new features.

Well, if your code was written against a version 9 API, you might want to stay with the stable API 9.81 track for now. You can still run your code against all (even the latest and beta) TWS and IBGW versions. It's a good practice to lock the API version in and to avoid automatic and uncontrolled version changes.
But by its nature, the stable track is a couple years old and is lacking the latest features version 10 provides. So you might want to start the development, unit, system, and regression testing cycles so that you can eventually move to the version 10 API.
