Attributeerror: Can't Get Attribute 'New_Block' On

I was using pyspark on AWS EMR (4 r5.xlarge as 4 workers, each has one executor and 4 cores), and I got AttributeError: Can't get attribute 'new_block' on <module 'pandas.core.internals.blocks'. Below is a snippet of the code that threw this error:

search =  SearchEngine(db_file_dir = "/tmp/db")
conn = sqlite3.connect("/tmp/db/simple_db.sqlite")
pdf_ = pd.read_sql_query('''select  zipcode, lat, lng, 
                        bounds_west, bounds_east, bounds_north, bounds_south from 
                        simple_zipcode''',conn)
brd_pdf = spark.sparkContext.broadcast(pdf_) 
conn.close()


@udf('string')
def get_zip_b(lat, lng):
    pdf = brd_pdf.value 
    out = pdf[(np.array(pdf["bounds_north"]) >= lat) & 
              (np.array(pdf["bounds_south"]) <= lat) & 
              (np.array(pdf['bounds_west']) <= lng) & 
              (np.array(pdf['bounds_east']) >= lng) ]
    if len(out):
        min_index = np.argmin( (np.array(out["lat"]) - lat)**2 + (np.array(out["lng"]) - lng)**2)
        zip_ = str(out["zipcode"].iloc[min_index])
    else:
        zip_ = 'bad'
    return zip_

df = df.withColumn('zipcode', get_zip_b(col("latitude"),col("longitude")))

Below is the traceback, where line 102, in get_zip_b refers to pdf = brd_pdf.value:

AttributeError: Can't get attribute 'new_block' on <module 'pandas.core.internals.blocks' from '/mnt/miniconda/lib/python3.9/site-packages/pandas/core/internals/blocks.py'>

Some observations and thought process:

1, After doing some search online, the AttributeError in pyspark seems to be caused by mismatched pandas versions between driver and workers?

2, But I ran the same code on two different datasets, one worked without any errors but the other didn't, which seems very strange and undeterministic, and it seems like the errors may not be caused by mismatched pandas versions. Otherwise, neither two datasets would succeed.

3, I then ran the same code on the successful dataset again, but this time with different spark configurations: setting spark.driver.memory from 2048M to 4192m, and it threw AttributeError.

4, In conclusion, I think the AttributeError has something to do with driver. But I can't tell how they are related from the error message, and how to fix it: AttributeError: Can't get attribute 'new_block' on <module 'pandas.core.internals.blocks'.
