Hello,

I am also running R 4.6 on Windows 11.
You can set a CRAN mirror in your etc/Profile.site file.
If you edit, you will see


# set a CRAN mirror
# local({r <- getOption("repos")
#       r["CRAN"] <- "http://my.local.cran"
#       options(repos=r)})


Substitute your mirror for 'my.local.cran'.

r["CRAN"] <- "https://cloud.r-project.org/"

works everywhere.
Then, uncomment the 'local' statement and restart R.

Hope this helps,
