The error seems from blockfrost:

{'error': 'Internal Server Error', 'message': 'An unexpected response was received from the backend.', 'status_code': 500}

The tx was signed and submitted, but blockfrost ran into an internal server error. Blockfrost might be able to provide you with more information about why it failed internally.

I think this is not an issue of pycardano, it is actually an issue of Blockfrost. We can not provide more details in case there is an internal server error at blockfrost.
