The solution there is adding the exception, not turning off Defender, especially when you don't have control over what other activities may take place on the system.

Exceptions are valid when scoped to a container where you reasonably expect to be the sole user of the data therein and it contains no executable code.

I honestly have never seen Defender behave with exceptions properly. Sometimes it does, sometimes it doesn't. Seems to depend on whether the day starts with a T.
