I had {tidymodels} loaded first, not sure if this would effect it: ✖ tidymodels::pkg_deps() masks pak::pkg_deps()

[ozanozbeker]

No, I restarted R without loading {tidymodels} and I got the same error.

This should not be an error, but splines is a base package, it comes with R, you cannot install it separately.
