Aaron is asking that you please include the output of sessionInfo() after loading the scater package. Here's mine:

where you can see I'm using a current R (version 4.0.2) and scater (1.16.2). It's also helpful to see

> BiocManager::version()
[1] '3.11'

to confirm use of the current version of Bioconductor, and

> BiocManager::valid()
[1] TRUE

to show that my packages are all from the current version of Bioconductor.
