@Mist_JawaYT @TheIndieBro btw this isn’t fixed yet but @Dudiing found a workaround. Select the widget you want to use in your Content Browser, then in your HUD Messenger’s Details Panel click the arrow in a circle icon to the right of the HUD Widget input window in order to “Use Selected Asset from Content Browser.” It works for me!
Thanks so much Dudiing!
