Exception java.lang.IllegalStateException

I was working with viewpager2 with tab layout . I am facing repeated crash due to IllegalStateException on playconsole.

Exception getting on Google Console
Exception java.lang.IllegalStateException: FragmentManager is already executing transactions at androidx.fragment.app.FragmentManager.ensureExecReady (FragmentManager.java:1931) at androidx.fragment.app.FragmentManager.execSingleAction (FragmentManager.java:1967) at androidx.fragment.app.BackStackRecord.commitNow (BackStackRecord.java:305) at androidx.viewpager2.adapter.FragmentStateAdapter.removeFragment (FragmentStateAdapter.java:464) at androidx.viewpager2.adapter.FragmentStateAdapter.gcFragments (FragmentStateAdapter.java:228) at androidx.viewpager2.adapter.FragmentStateAdapter.restoreState (FragmentStateAdapter.java:569) at androidx.viewpager2.widget.ViewPager2.restorePendingState (ViewPager2.java:350) at androidx.viewpager2.widget.ViewPager2.dispatchRestoreInstanceState (ViewPager2.java:375) at android.view.ViewGroup.dispatchRestoreInstanceState (ViewGroup.java:3829) at android.view.View.restoreHierarchyState (View.java:18613) at androidx.fragment.app.Fragment.restoreViewState (Fragment.java:639) at androidx.fragment.app.Fragment.restoreViewState (Fragment.java:3010) at androidx.fragment.app.Fragment.performActivityCreated (Fragment.java:3001) at androidx.fragment.app.FragmentStateManager.activityCreated (FragmentStateManager.java:580) at androidx.fragment.app.FragmentStateManager.moveToExpectedState (FragmentStateManager.java:285) at androidx.fragment.app.FragmentStore.moveToExpectedState (FragmentStore.java:112) at androidx.fragment.app.FragmentManager.moveToState (FragmentManager.java:1647) at androidx.fragment.app.FragmentManager.dispatchStateChange (FragmentManager.java:3128) at androidx.fragment.app.FragmentManager.dispatchActivityCreated (FragmentManager.java:3072) at androidx.fragment.app.FragmentController.dispatchActivityCreated (FragmentController.java:251) at androidx.fragment.app.FragmentActivity.onStart (FragmentActivity.java:501) at androidx.appcompat.app.AppCompatActivity.onStart (AppCompatActivity.java:246) at android.app.Instrumentation.callActivityOnStart (Instrumentation.java:1392) at android.app.Activity.performStart (Activity.java:7252) at android.app.ActivityThread.handleStartActivity (ActivityThread.java:2970) at android.app.servertransaction.TransactionExecutor.performLifecycleSequence (TransactionExecutor.java:180) at android.app.servertransaction.TransactionExecutor.cycleToPath (TransactionExecutor.java:165) at android.app.servertransaction.TransactionExecutor.executeLifecycleState (TransactionExecutor.java:142) at android.app.servertransaction.TransactionExecutor.execute (TransactionExecutor.java:70) at android.app.ActivityThread$H.handleMessage (ActivityThread.java:1831) at android.os.Handler.dispatchMessage (Handler.java:106) at android.os.Looper.loop (Looper.java:201) at android.app.ActivityThread.main (ActivityThread.java:6826) at java.lang.reflect.Method.invoke (Method.java) at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run (RuntimeInit.java:547) at com.android.internal.os.ZygoteInit.main (ZygoteInit.java:873)

Here is my working Code in Fragment

TabLayoutMediator(binding.tablayout,binding.viewpagerSeeAll) { tab, position ->
            tab.text= " ${Constants.categories.get(position).displayName}"
        }.attach()
        binding.crossAdBackground.setOnClickListener {
            if (Constants.isUserFree()) {
                Util.proPopup(true, requireContext()!!, firabaseAnalytics, editActivityUtils)
            } else
                prefManager.let { Util.goToProMethod(requireActivity(), it) }
        }

Viewpager Adapter Code

 inner class  ViewPagerAdapter(categories: ArrayList<TemplateCategory>, fragment:Fragment): FragmentStateAdapter(fragment) {
        var categories: ArrayList<TemplateCategory> = categories
        override fun getItemCount(): Int {
            return  categories.size

        }
        override fun createFragment(position: Int): Fragment {
            val fragment = ViewPagerItemFragment()
            val args = Bundle()
            args.putParcelable(TemplateCatDetail.ARG_PARAM2, categories.get(position))
            args.putInt(TemplateCatDetail.ARG_PARAM3, position)
            args.putString(
                TemplateCatDetail.ARG_PARAM4,
                Constants.categories[position].displayName
            )
            fragment.arguments = args
            return fragment
        }
    }
