#unable to compile tutorial "tools"

Does anyone know how to compile this? I have already downloaded all the necessary packages and software.

Quitting from lines 74-79 (tutorial.Rmd)

Error in readPNG(file) :

unable to open C:/Users/chris/Documents/R/win-library/4.0/primer.tutorials/imagespwd.png

Calls: sourceWithProgress ... withCallingHandlers -> withVisible -> eval -> eval -> readPNG

Execution halted

I am also interested if anyone has input toward this! The latter series of messages is given when the tutorial compiler hangs up at ~20% completion. I've tried to update the 'png' package and any/all other constituent packages.
