- Does your application include asynchronous method calls during navigation?
- Does this problem occur on a local emulator?
Your prompt reply will be highly appreciated.

When navigating to a new page, which method you called? And do you check if some parameters are null when creating the new page? Also, please try to add the following on .csproj file.
<PropertyGroup Condition="$(TargetFramework.Contains('-ios')) and '$(Configuration)' == 'Release'"> <MtouchInterpreter>all</MtouchInterpreter> </PropertyGroup> -

With the same code base, app was not crashing in android. I will add MtouchInterpreter and see if any things pops up in the crash log

2024-12-24T05:30:55.9133333+00:00 Without context it is difficult to determine which platformview was null.
And we can see the error occurs on the following methods
TLM.NextGenMobileApp.Mobile.ViewModels.ManagerPTO.ManagerPTOListViewModel.HandlePTONavigation(ManagerPTODetailsPage managerPTODetailsPage)TLM.NextGenMobileApp.Mobile.ViewModels.ManagerPTO.ManagerPTOListViewModel.HandlePTODrawBottomSheet(PTORequestDetails parameter)Could you share more code snippets about the methods? And what's the
ManagerPTODetailsPage, do you use handler on this page? -

App is getting the crash on highlighted(bolded) line.
private async Task HandlePTONavigation(ManagerPTODetailsPage managerPTODetailsPage)
{ var homePage = Application.Current.MainPage.Navigation.NavigationStack.Last() as Pages.Home.HomePage; if (homePage != null) { **await homePage.CurrentPage.Navigation.PushAsync(managerPTODetailsPage);** } else { await Application.Current.MainPage.Navigation.PushAsync(managerPTODetailsPage); } } -
