   同じソースコードでビルドを少なくとも２回実行している、と言っていますね。
   
   もしかしたら、同じことを２回実行したのではないでしょうか？

   上の画像を見直してみましたが、
   
   git push heroku master
   
   で push していますよね？
   
   エラーメッセージを見ると
   
   git push heroku <branchname>:main
   
   で push しろ、と書いてあります。
   （heroku 側のブランチが master ではなく main になっているみたいです）
   
   git push heroku master:main
   
   とやってみてもらえますか

   エラーメッセージを見ると
   
   Your bundle only supports platforms ["x86_64-darwin-20"] but your local platform is x86_64-linux.
   Add the current platform to the lockfile with `bundle lock --add-platform x86_64-linux` and try again.
   
   とあります。
   
   bundle が "x86_64-darwin-20" 、つまり Mac 用を指定しているけど、Heroku 側は Linux なので動かせないよ、と言っていますね。
   
   そのあとのエラーメッセージに書いてある通り
   
   bundle lock --add-platform x86_64-linux
   
   を実行して、変更されたファイル（多分 Gemfile.lock）をcommitして、pushし直せばよいと思います。
   
   基本的に、エラーメッセージに原因（と対策）が書いてあるので、まずはエラーメッセージを読んでみるとどう対策すればわかると思います。
