Steps to Reproduce

  await SentryFlutter.init(
        (options) {
      options.dsn = '<ON_PREM_SENTRY_DSN>';

      options.environment = '${kIsProd ? "PROD" : "UAT"}/${kReleaseMode ? 'Release' : kProfileMode ? 'Profile' : 'Debug'}';
      // Adds request headers and IP for users, for more info visit:
      // https://docs.sentry.io/platforms/dart/guides/flutter/data-management/data-collected/
      options.sendDefaultPii = true;
      // Set tracesSampleRate to 1.0 to capture 100% of transactions for tracing.
      // We recommend adjusting this value in production.
      options.tracesSampleRate = 1.0;
      // The sampling rate for profiling is relative to tracesSampleRate
      // Setting to 1.0 will profile 100% of sampled transactions:
      // Note: Profiling alpha is available for iOS and macOS since SDK version 7.12.0
      options.profilesSampleRate = 1.0;
      // Enable logs to be sent to Sentry
      options.enableLogs = true;
      // Record session replays for 100% of errors and 10% of sessions
      options.replay.onErrorSampleRate = 1.0;
      options.replay.sessionSampleRate = 0.1;
    },
    appRunner: () => runApp(
      SentryWidget(
        child: MyApp(),
      ),
    ),
  );

on running the app using flutter run --profile on my physical iphone 17, the app launches but then does not proceed to the initial screen, it just freezes.

i am using an on-prem sentry instance

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '+[PrivateSentrySDKOnly startProfilerForTrace:]: unrecognized selector sent to class 0x104fc5d48'

Expected Result

I was trying to run the app on profile mode to profile the app. as only iOS is supported and not android but the app should have worked and i should have received some logs in the profiling section

The rest of the features of sentry are all working fine

Actual Result

The app freezes

can you try removing the profilesSampleRate and check if it works?
