Dockerでubuntu・pythonをビルドした時のエラー

実現したいこと

Dockerでubuntu・pythonを導入した環境を構築したいです。

【環境】
Windows10
Docker Desktop 4.28.0

発生している問題・分からないこと

「docker build -t myapp:1.0 .」を実行するとエラーが出てしまい、イメージが作成できません。

数ヶ月前は普通にできていたので、なぜできなくなったのかが、不明です。
また、PaasサービスであるRailwayでのビルドはうまく行くようなので、ローカルのみおかしいようです。

当方、初心者のためわからない事が多く（特にDocker関連）初心者でもわかるように教えていただけると幸いです。。。
