Rails 8.1.1 Ruby 3.4.0 no implicit conversion of Array into Integer (TypeError)

I get the following error when starting rails console in Rails 8.1.1 and Ruby 3.4.0
./console Array values in the parameter toGem.paths=` are deprecated.
Please use a String or nil.
An Array ({"GEM_PATH" => ["/home/pst/.rbenv/versions/3.4.7/lib/ruby/gems/3.4.0", "/home/pst/.local/share/gem/ruby/3.4.0"]}) was passed in from bin/rails:3:in 'Kernel#load'

    x, w, content = new_items[level]
                              ^^^^^
    from /home/pst/.rbenv/versions/3.4.7/lib/ruby/gems/3.4.0/gems/reline-0.6.3/lib/reline/line_editor.rb:410:in 'Array#each'

`
new_items is [0, 19, "pst(\e[34mdev\e[0m):001> "], [19, 0, ""]]
and level is [0, nil]
in that case

Start by reproducing the failure with Rails console on Ruby 3.4.0, then inspect reline/line_editor.rb around lines 410-418. Trace how new_items and level become [0, nil], and verify the rendering path no longer raises the reported TypeError for that input.
