Error when restarting napari-animation

[haesleinhuepf]

When starting the napari animation wizzard twice (and closing the widget after the first attempt): The error below shows up. One can continue using napari-animation only after restarting napari. It does not matter if the plugin is called from the Plugins or the Tools > Visualization menu.
