Error installing packages using Julia 1.9

I use Julia 1.9 and have run into a problem following the Getting Started Video: I get an error after calling Pkg.build("RCall")

julia> Pkg.build("RCall")
ERROR: Could not find either `git-tree-sha1` or `path` for package DelimitedFiles

Reproduce the exact Pkg.build("RCall") command with Julia 1.9, then start at the Pkg.build and build_versions entries shown in the stack trace. Check the reported DelimitedFiles package error and the Getting Started Video setup; done means the package installation completes without this error.
