A new version of TeX Live has been released. If you need to install or update any LaTeX packages, you have to upgrade TinyTeX with tinytex::reinstall_tinytex(). If it fails to upgrade, you might be using a default random CTAN mirror that has not been fully synced to the main CTAN repository, and you need to wait for a few more days or use a CTAN mirror that is known to be up-to-date (see the "repository" argument on the help page ?tinytex::install_tinytex()).
tlmgr.pl: Local TeX Live (2020) is older than remote repository (2021).
Cross release updates are only supported with
