EXC_BAD_ACCESS (SIGSEGV) crash

Hi Friends. With the new iOS 16.2 update in my iPad device, my app started failing. It works in simulator but fails in real device. Below are the device logs : Tried searching various forums, tried address santizer and zombies but couldn't find useful. I am a bit newbie to Xcode so not so knowledge on how to debug. Can anyone help me on how can I determine place of error and possible fix from the log. thanks in advance
