App crashing while connecting Yubikey when app is prompting to connect

[nickqlx]

App is crashing in YKFAccessoryConnection.m file and Xcode is pointing it to the below method as
Thread 1: EXC_BAD_ACCESS (code=1, address=0x940e92a3b930)

• (void)accessoryDidConnect:(NSNotification *)notification {
  EAAccessory *accessory = [[notification userInfo] objectForKey:EAAccessoryKey];
  if (![self shouldAcceptAccessory:accessory]) { // Here App is crashing
  return;
  }

Here I have attached a screenshot of the Xcode crash. I am using the latest library yubikit-ios-4.3.0 and using yubico-ctk-extension demo code. My project is in objective c so I linked the source in my project as mentioned in the Readme notes.

Note: I am not using Cocoapods or Swift package dependency. I have added the library manually and using it. Also, it only crashes when I try to connect 5Ci Yubikey after I get a prompt for connection. If Yubikey is already connected then the connection is established successfully also it worked with NFC Yubikey in all ways.

I found the problem. Somehow YKFAccessoryConnectionConfiguration object is released every time this scenario happens. Can you please help me to solve this? I don't understand what I am doing wrong.
