やったこと

普段触らないファイルのLoadErrorなのでbundlerのバージョンを疑ったりしましたが解決せず。

結論、Ruby3.1で標準ライブラリからいくつかのライブラリが除外されていたことが原因でした。
文字通りのcannot load such fileでした…。

引用元:https://www.ruby-lang.org/ja/news/2021/12/25/ruby-3-1-0-released/

以下のライブラリが新たに bundled gems になりました。Bundler から利用する場合は Gemfile に明示的に指定してください。
net-ftp 0.1.3
net-imap 0.2.2
net-pop 0.1.1
net-smtp 0.3.1
matrix 0.4.2
prime 0.1.2
debug 1.4.0

以下3点を手動で追加したら解決しました。

gem 'net-imap'
gem 'net-pop'
gem 'net-smtp'
