SmartCard pairing does not work

Hi,

as the topic says, the SmartCard pairing and PIN dialogues don't show up on my system. We have configured other Macs with an identical setup and those machines work fine.

Using OpenSC for access to the cards it works fine.

Also, the necessary Root and Intermediate certs are installed in the system keychain

What I've checked/tested so far:

1. pcsctest - successful
2. pkcs11-tool --login --test - works
3. pkcs11-tool --list-objects - works
4. system_profiler SPSmartCardsDataType - shows all the certs
5. sc_auth identities - lists identities
6. sc_auth pairing_ui -s status - enabled
7. security list-smartcards - lists the smartcard
8. security smartcards token -l - is empty
9. Clean install of macOS - issue still exists
10. Reset SMC - issue still exists

Here's the errors I was able to find:

sc_auth verifypin

Verifying PIN of SmartCard in reader Certgate AirID via BLE

ERROR: Unable to select card application AID {length = 11, bytes = 0xa000000308000010000100}

sc_auth pairing_ui

Hangs

sc_auth pairing_ui -f

Causes ctkbind to throw this message:

No RSA decryption key or ECDH key was found for token: org.opensc-project.mac.opensctoken.OpenSCTokenApp.OpenSCToken:f4d79630d09b7cfdb1ffd95cc5f32981

<Insert the Card>

Console.app shows this error for ctkbind (as above):

No RSA decryption key or ECDH key was found for token: org.opensc-project.mac.opensctoken.OpenSCTokenApp.OpenSCToken:f4d79630d09b7cfdb1ffd95cc5f32981

I appreciate any help on this topic.
