Thanks for reporting your issue, this behavior is expected: In 2023.7.1, we added a feature that by casts object columns to the pyarrow[string] dtype by default. Most users are using the object dtype for strings and this cast translates to a major performance gain (both memory and runtime) for them.
You can disable this behavior with dask.config.set({"dataframe.convert-string": False}).
