Herokuをアップデートするとデプロイできなくなりました

Herokuでデプロイする際にエラーになります。

初めて質問させていただきます。
宜しくお願いし致します。

Djangoで作成したアプリケーションをHerokuにデプロイする際にエラーが出ます。
アップデートをする前ではデプロイできたにもかかわらず、22stackの更新をおこなってからデプロイをする事ができなくなりました。
初めて作るアプリケーションなので、最後までデプロイしたいと思っています。

環境
Windows11
Python3.10.8
Vscode

試したこと

buildpacksの更新
推奨環境への変更（Python3.9.13→Python3.10.8）※runtime.txtの更新
requirements.txt の確認
heroku ecoDyno・PosgreSQLの有料プランへの加入
