The 4 series R has been released as a "developmental version" for a year.
Some CRAN / github installation of basic R packages (dyplr, tidyverse) took this version as default, but Biocondunctor packages (e.g. biomaRt) are still with 3.6+。
I met some version issues, and fixed with downgrading dplyr and reinstalling BiocManager::install(version = "3.10").
