From the HyperAPI release notes:

November 3rd, 2021
Reading Apache Parquet files is now officially supported and no longer has to be enabled through the use of the process setting experimental_external_format_parquet.

The setting no longer exists, you have to remove it from the parameters you pass to the HyperProcess constructor.
