I can't reproduce the problem myself but in a seminar of 8 students I was teaching, about half of them were having this error. Here is an example from one of them, with a stop(error=recover) trace. Below I include some other with cleaner sessionInfo() (I asked everyone to use reprex on this code but not everyone did...) If there's more information that would be useful from one of the students seeing this error, let me know.
