Weird Pushasync Bug on physical device

### Description

When I run the project on debug mode on the physical device the app seems fine but has delayed for like 1-2 seconds before pushing it to another page.

But when I ran the installed app on a physical device and not debugged it, calling Pushasync or even Pushmodalasync crashes the app.

### Steps to Reproduce

Here is the link for the said app.

https://github.com/L10Messi10/iRentMeMAUI

### Version with bug

6.0.400 (current)

### Last version that worked well

Unknown/Other

### Affected platforms

Android

### Affected platform versions

Android 11

### Did you find any workaround?

No, I've uninstalled all NuGet packages but still, the issue exists.

### Relevant log output

_No response_

Start with the linked iRentMeMAUI reproduction app and run it on Android 11 using MAUI version 6.0.400, comparing debug and installed builds. Investigate the crash when calling PushAsync or PushModalAsync and capture relevant log output; done means reproducing the failure and identifying a reliable fix or clear diagnostic.
