Reiner cyberjack stops working in banking software when nitrokey pro 3 is plugged in

When I try to do an electronic transfer in my banking software (moneyplex) and my Reiner cyberjack card reader, I get the message “No Card detected”.
However, everything works fine if I remove my Nitrokey Pro 3.
Is there a way to use both at the same time or are they mutually exclusive?
(OS. Linux Mint 21.2 Victoria)

Maybe the software has a problem figuring out which card reader is the “first”?
