Describe the actual behavior

Crash when using "segmentation mask" on iOS

Describe the expected behaviour

We would like to have the "segmentation mask" working

Standalone code/steps you may have used to try to get what you need

We're experiencing an issue when using the Pose Landmark Detection (https://developers.google.com/mediapipe/solutions/vision/pose_landmarker) with the "segmentation mask" enabled on iOS and iPadOS 17.4.1. This feature works without any problems on Windows and Android. However, on iOS, enabling the segmentation mask causes the app to crash.

The crash occurs randomly after varying usage times. Sometimes, it works fine for several minutes, but often crashes within a few seconds. The issue seems to happen more quickly on older devices, but using a newer device doesn't guarantee stability.

We would appreciate any assistance or advice you can provide in addressing this issue. Please let me know if you require any additional information.
