UseSentry or SentrySdk.Init call
.UseSentry(options =>
{
options.Dsn = "";
options.TracesSampleRate = 1;
options.DisableUnobservedTaskExceptionCapture();
options.SetBeforeSend((e, hint) =>

Steps to Reproduce
- Run a maui app in release mode that uses navigation page rather than shell
- Navigate between pages that have text entry's
Expected Result
The app doesn't crash
Actual Result
The app occasionally crashes with an object disposed exception when navigating between pages in the app. Removing sentry from app stops it crashing. These crashes did not happen when our app was built with .net 8.
The Maui control mentioned in the first line varies but the below stack trace is the most prolific. My guess is that Sentry is doing something when the page is unloaded.
