produces the following error on rstudio.cloud:

One student also got the following warning on trying to load the
rmapshaper package mentioned in the snippet:
Warning: v8 Engine is version 184.108.40.206 but version >=6 is required for full functionality. Some rmapshaper functions, notably ms_clip() and ms_erase(), may not work. See https://github.com/jeroen/V8 for help installing a modern version of v8 on your operating system.
Could these be related issues?
Update: One student found a workaround by using
oz_votes <- ozmaps::abs_ced
instead, but I'm not sure what accounts for it working.
