Every time I try to install Org.Hs.eg.db, i get this error- ERROR: lazy loading failed for package 'org.Hs.eg.db' and I'm not sure what to do about it. Does anyone have any advice?

BiocManager::install("org.Hs.eg.db")

It should just install.

You might have something that gets loaded into the .GlobalEnv that is affecting things, so you could start R with the --vanilla flag for a clean environment and then try installing.
