Try to add @MainActor

view.visualEffect { @MainActor content, proxy in
    content.distortionEffect(
        ShaderLibrary.complexWave(
            .float(startDate.timeIntervalSinceNow),
            .float2(proxy.size),
            .float(0.5),
            .float(8),
            .float(10)
        ),
        maxSampleOffset: CGSize(width: 100, height: 100),
        isEnabled: hasComplexWave
    )
}
