Warning message: file_renderer failed to copy frames to the destination directory

[vpoguru]

macOS 10.15.5
R 4.0.1
ggplot2 3.3.2
gganimate 1.0.5

When running the first example from the gganimate website, the animation is not generated. I get the "Warning message: file_renderer failed to copy frames to the destination directory ". However, the 100 png files are created.

When writing the result from ggplot into a variable (p) and run the animate function ...

animate(p)

... I see the same error message.

When adding the default parameter renderer = gifski_renderer() ...

animate(p, renderer = gifski_renderer())

... it works.

I can reproduce this in ubuntu 18.04.4, (Updated to R 4.0.2, gganimate and other stuffs, no warning anymore)
