This crash is occurring on iOS 26.2 using an iPhone 17 Pro. It is a known issue in the Fabric (New Architecture) C++ layer of React Native when interacting with the RNCSlider component. Wikipedia Wikipedia +2 The crash is triggered by _UIFluidSliderInteraction (part of the Liquid Glass UI redesign in iOS 26) when it attempts to dispatch a value change event to a React component that may no longer be valid in the shadow tree.
