Blank screen when viewing session replay recordings

[danielogunsdev]

Version

4.9.0

Steps to Reproduce

1. Run the Flutter app and initialize Posthog using the code below in the main file.
2. Navigate through the application.
3. Check the session replay recording on Posthog.

Code
final config = PostHogConfig(env.postHogApiKey);
config.debug = env.flavor != BuildFlavor.prod;
config.captureApplicationLifecycleEvents = false;
config.host = env.postHogApiHost;
config.sessionReplay = true;
config.sessionReplayConfig.maskAllTexts = false;
config.sessionReplayConfig.maskAllImages = false;
config.sessionReplayConfig.throttleDelay = const Duration(milliseconds: 1000);
config.flushAt = 1;
await Posthog().setup(config);

Expected Result

I expect to see the session replay (screenshots) on the Posthog session replay recording page without encountering a blank screen.

Actual Result

The session replay recording page only displays a blank screen.
