Steps to Reproduce

Repro app : https://github.com/tranb3r/Issues/tree/main/MauiAppSegfault

1. Open repro app in Visual Studio and set your Dsn for Sentry before running the app. Check Sentry.Maui version in csproj.
2. Run the app in Release mode on Android.
3. Tap on Run button. A NullReferenceException happens.
4. With Sentry.Maui 4.x, the exception is catched silently. Close the app, launch it again. An error report with SIGSEGV is sent to Sentry immediately.
5. With Sentry.Maui 5.0.0, even if the exception is catched, the app crashes. Launch the app again. An error report with SIGSEGV is sent to Sentry.

Expected Result

No crash. No SIGSEGV report by Sentry.

Actual Result

With 4.x : no crash but SIGSEGV report by Sentry.
With 5.0 : app crashes and SIGSEGV report is sent by Sentry.
Without Sentry.Maui : no crash (exception is catched).
