Reproduction Example/SDK Setup

Sentry.init({
  dsn: process.env.NEXT_PUBLIC_SENTRY_DSN,
  release: process.env.NEXT_PUBLIC_SENTRY_RELEASE,
  environment: djangoEnv,
  tracesSampleRate: 1.0,
  replaysOnErrorSampleRate: 1.0,
  replaysSessionSampleRate: 1.0,
  tracePropagationTargets: djangoBackendUrls,
  integrations: [
    Sentry.browserTracingIntegration(),
    Sentry.replayIntegration({
      maskAllText: false,
      blockAllMedia: false,
      maskAllInputs: false,
      networkDetailAllowUrls: djangoBackendUrls,
    }),
  ],
  beforeSend: (event, hint) => {
    console.error(hint.originalException ?? hint.syntheticException);

    if (process.env.NEXT_PUBLIC_SENTRY_DSN) {
      return event;
    } else {
      // drop the event
      return null;
    }
  },
  beforeBreadcrumb: (breadcrumb, hint) => excludeGraphQLFetch(breadcrumb, hint),
});

Steps to Reproduce

We just see these come in all the time. This is a list of replays logged in the last seven days, ordered by duration. As you can see, some are almost 100 hours long:

Also, the replays themselves just show our loading screen for the entire replay.

Expected Result

All replays should be under an hour, and show normal activity.

Actual Result

See above.

Just noting here that I'm upgrading to 8.33.x today and will report back whether #13815 seems to fix the issue or not.

@alimony It's unlikely to fix your issue, i believe the actual problem is #13872
