Plotting RasterStack with ggRGB(), Error in grid.Call.graphics cannot allocate memory block of size 67108864 Tb

I am trying to plot a RasterStack using ggRGB but I am getting the error:

Error in grid.Call.graphics(C_raster, x$raster, x$x, x$y, x$width, x$height, : cannot allocate memory block of size 67108864 Tb

The RasterSTack imported is only 13 mb so I'm assuming this is a coding issue.

My code:

library(ggplot2)
library(ggmap)
library(RStoolbox)
library(raster)

BVTWaer <- raster::stack("E:/R/DataViz/shapefiles/BVTW/BeaverViz2.tif")
> BVTWaer
class      : RasterStack 
dimensions : 1819, 2623, 4771237, 3  (nrow, ncol, ncell, nlayers)
resolution : 1, 1  (x, y)
extent     : 0, 2623, 0, 1819  (xmin, xmax, ymin, ymax)
crs        : NA 
names      : BeaverViz2.1, BeaverViz2.2, BeaverViz2.3 
min values :            0,            0,            0 
max values :          255,          255,          255 

ggplot() +
  ggRGB(img = BVTWaer,
        r = 1, g = 2, b = 3,
        maxpixels = 5e+10,
        ggLayer = TRUE)
