Error occuring at the "Generating train split" stage when downloading the entire dataset.

Hello guys,
I tried to download the entire dataset locally using
load_dataset("tobiolatunji/afrispeech-200", "all", streaming=False)
The downloading and extracting phases succeeded; nevertheless, an error occurs at the "Generating train split" step and always at the 35,999 th sample. The full traceback is the following:

DatasetGenerationError: An error occurred while generating the datasetNB:
- I have more than enough space on my hard drive.
- I believe it is not a RAM memory issue since it did not get full during the execution of the code.
- I decided not to use the streaming mode because when I do so, it takes ~1h only to fetch/read the data before starting with the training loop. It results in a slow training process.
Any help would highly be appreciated.
Thanks.
If hard drive space is not a limitation, can you use the google drive data download method while we resolve this issue with the Huggingface team?
Sure, I did not think of it.
Thanks.
