The current MinGW workflow in Ruby shows:

skipped bundled gems:
    csv-3.3.4.gem                   not found in bundled_gems

I verified the same locally with both a Windows UCRT build and an Ubuntu build, and the ruby-loco builds are also failing.

The current line in bundled_gems:

csv                 3.3.3   https://github.com/ruby/csv e0874e47e2730dacccdb0c534a2cdc073d3bdaea

If one changes that to the below, ruby-loco builds pass.

csv                 3.3.4   https://github.com/ruby/csv e0874e47e2730dacccdb0c534a2cdc073d3bdaea

But, Ruby's CI fails in the ./.github/actions/setup/directories step.

I have a GitHub repo github-actions-ruby-info that logs information about Ruby builds on most GHA supported platforms.

None of the current Ubuntu and macOS head builds have csv installed. The current ruby-loco builds have csv installed, as I patched it earlier today.
