[dschuermann]

@papin97 what kind of security key are you using?

[papin97]

@dschuermann It's YubiKey 5 NFC

[dschuermann]

I suspect this problem is related to your Android device, since the YubiKey 5 NFC does work with other devices.
In the next version, the issue will not lead to a crash. Instead the error code will be reported in the user interface.

[papin97]

Maybe this issue from another NFC project will help
