Yes, see <https://github.com/thomasp85/gganimate/issues/517>.

When gganimate:::draw_frames() tries to plot$scene$plot_frame(), an 
error happens

     Error in labs(!!!lapply(plot$plot$labels, function(label) { :
       could not find function "labs"

but that is caught and turned into a "Failed to plot frame" warning 
(that would be shown in the rendered vignette), so gganimate only fails 
later when it calls its gifski_renderer() with non-existent png files 
and that is the error we get to see in the build log.
