[BUG] DeleteSlot / DeleteSlotConfiguration throws fault when not failing

[virot]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

When calling DeleteSlot(Slot slot), it removes the configuration, but also returns an exception.
System.InvalidOperationException: YubiKey Operation Failed [Warning, state of non-volatile memory is unchanged.] at Yubico.YubiKey.Otp.Operations.DeleteSlotConfiguration.ExecuteOperation() at Yubico.YubiKey.Otp.Operations.OperationBase1.Execute()
at Yubico.YubiKey.Otp.OtpSession.DeleteSlot(Slot slot)`

This is a bit similar to #48, but no COM code involved. I have reduced the issue to a small amount of code..
https://github.com/virot/YubiKeyTests/blob/main/OTP_Remove_throws/Program.cs

If I enable the SDK Debugging code I see the following:
info: Yubico.YubiKey.Oath.OathSession[0] Connecting to Otp info: Yubico.YubiKey.Oath.OathSession[0] Connected to Otp info: Yubico.Core.Devices.Hid.IHidConnection[0] Reading the OTP status. info: Yubico.Core.Devices.Hid.WindowsHidDevice[0] Updating last used for HID:1050:0407 Usage:Keyboard \\?\HID#VID_1050&PID_0407&MI_00#8&57ad29&0&0000#{4d1e55b2-f16f-11cf-88cb-001111000030}\KBD to 01:27:46.8005131 Configuration state of ShortPress: False warn: Yubico.YubiKey.Oath.OathSession[0] Exception caught when disposing Session: System.NotSupportedException, A YubiOTP APDU was received with instruction number 164. This instruction is not supported.

So it seems that it is doing what should be done, removing the configuration then it throws a fault.

Expected Behavior

It should remove the configuration and dont throw a fault.

Steps To Reproduce

• Clone / download
• Build
• Run with a YubiKey (I have seen this complete on a FW 5.4.3, but then start to fail time after time.)

Version

1.12.1

Version

5.7.1

Anything else?

Works on 5.4.3

Fails on 5.7.1
