Hello,

I can reproduce this issue in MAUI.

I use same code. it is works in the Xamarin.

This issue is reported in MAUI GitHub page, please waiting for PG's update in these threads.

Make Shell compatible with the other page types in .NET MAUI

Android Pushing TabbedPage from Shell-based ContentPage causes NRE. #7615

Here is a workaround, you can use Navigation.PushModalAsync to navigate shell to tabbedpage.

await Navigation.PushModalAsync(new TabbedPage1());

Best Regards,
