NXP's NFC card reader PNEV512R (https://www.nxp.com/products/rfid-nfc/nfc-hf/nfc-readers/explore-nfc-exclusive-from-element14:PNEV512R) does not work with my new raspberry pi 4.

For installing the needed software I followed this manual: https://github.com/svvitale/nxppy
Installation was without any fails. But even the instantiation of Mifare raises an exception.
Python Code:
import nxppy
mifare=nxppy.Mifare()
Exception:
nxppy.InitError: Nxppy: Unknown Error from Undefined Component
The above exception was the direct cause of the following exception:
Traceback (most recent call last):
File "nfc.py", line 3, in <module>
mifare=nxppy.Mifare()
SystemError: <class 'nxppy.Mifare'> returned a result with an error set
The SPI was switched on of course. ^^ And I tested the interface with the loopbacktest: https://elinux.org/RPi_SPI
So SPI is working. On my Raspbarry Pi 3B+ everything works fine. Now I am looking for a solution to fix this problem.
