Anything notable precede the failure of the window drop and convertible top operation? Did both fail at exactly the same time? Or did you buy the car this way?

Had you done some coding or programming shortly before the failures? Had the battery disconnected for any length of time? There are a number of entries in the FRM relating to the window drop on door opening (which is not the same as anti-trap) which might have been affected.

How do you know the rear windows need Hall sensors replaced?

Have you read error codes for all modules with INPA or ISTA/D? If not, do so and report them here.
