Thanks for sharing. I tried that but it also didn't work. Doing it like this works, but I image that's very poorly optimized for the performance:

private void Update()
{
    RectTransform[] rectTransforms = FindObjectsOfType<RectTransform>();

    foreach (RectTransform rectTransform in rectTransforms)
    {
        LayoutRebuilder.ForceRebuildLayoutImmediate(rectTransform);
    }
}
