I am getting below crash logs across all iOS versions. However, I am not able to figure out the exact cause of this. Is it something to do with accessing a de-allocated object? If yes, is there a way to replicate the scenario since I am not able to.

Also I am not able to figure out where exactly the crash is happening. Since I am getting these as part of release build.
