saveBackStack FragmentTransactions must use setReorderingAllowed(true). Found BackStackEntry{} that did not use setReorderingAllowed(true)

Question

A HomeActivity class has a bottom menu navigation which opens up a fragment class. Everything is good to navigate inside the fragment class. However, when I click any other bottom menu navigation item from this fragment class, it immediately crashes and results with the below error,

2022-12-07 10:39:41.828  8956-8956  AndroidRuntime pid-8956

java.lang.IllegalArgumentException: saveBackStack("f1a147ba-4bb3-449c-87b8-cf73f7bf463c") included 
FragmentTransactions must use setReorderingAllowed(true) to ensure that the back stack can be
restored as an atomic operation. 
Found BackStackEntry{82b1a #1} that did not use setReorderingAllowed(true).

In my fragment class, I tried to return the same view in onCreateView()

if (fragmentView != null) {
            return fragmentView;
}

Also added 'context' in onResume() for my fragment class

var mContext: FragmentActivity? = FragmentActivity()

mContext = this!!.getActivity() as HomeActivity

mContext.bottomItems()

and nothing worked so far. With this log information couldn't find much on where and what exactly went wrong.

I found this Stack overflow link app-crashes-when-tapping-multiple-times-on-bottom-navigation-views that somewhat relates to my issue however the error between mine and this link is different here

Found BackStackEntry{82b1a #1} that did not use setReorderingAllowed(true).

Adding Code For Understanding, From Home screen user clicks the bottom navigation which shows the FirstFragment screen. The Firstfragment contains few tabviews where you see the SecondFragment information called in observeResponse() method in the class FirstFragment.kt being called will get loaded.
