An enormous and sincere thank you to all of you! I will make sure her mac os is updated and have her remove the above directories/files. Hopefully that will do the trick, but if not I will open an issue at github. And yes - she tried Cocalc and it got her able to submit her assignment tonight, at least!
Thank you again!!!
