Polygon edge and font problems

Running this script today I have the following error thrown up:

Error in grid.Call(C_textBounds, as.graphicsAnnot(x$label), x$x, x$y, : polygon edge not found In addition: Warning messages: 1: In grid.Call(C_textBounds, as.graphicsAnnot(x$label), x$x, x$y, : no font could be found for family "Arial" 2: In grid.Call(C_textBounds, as.graphicsAnnot(x$label), x$x, x$y, : no font could be found for family "Arial" 3: In grid.Call(C_textBounds, as.graphicsAnnot(x$label), x$x, x$y, : no font could be found for family "Arial"

Updating ggplot and scales packages didn't fix the issue.

Seems online others have come across this problem where R can't access a font. I tried these options out, but no luck:

This is another option, but it seems less likely:

I'm working on a solution.
