Missing DICOM file Meta Information

Hi,
I am trying to convert the DICOM metadata to a pandas dataframe using the code below

 df = pd.DataFrame.from_dicom(items, n_workers = 8, threadpool = True)

but i receive the error message below

InvalidDicomError: File is missing DICOM File Meta Information header or the 'DICM' prefix is missing from the header. Use force=True to force reading.

Here is the traceback

The pydicom version installed is 2.0.0
May you please assist me in diagnosing this problem
Thanks
