ModuleNotFoundError: No module named 'dataclasses' when import refinitiv.dataplatform as rdp

When I tried to import the package (import refinitiv.dataplatform as rdp), I kept telling that data classes could not be found. I reinstalled refinitiv-dataplatform several times and still got the same result.

It has not yet progressed to the verification step. The first step is to import the development package, there is a problem, please see the screenshot.
