Unityを開いたら、「ArgumentNullException: Value cannot be null.」というエラーが出ることに関して

前提・実現したいこと

・Unityで新規プロジェクトを作成
・以下のエラーが出た
・Unityを再インストール：変化なし
・UnityHubを再インストール：変化なし

ここに質問の内容を詳しく書いてください。
Unityでゲーム開発をしています。
確かかわかりませんが、他人のプロジェクトをZipファイルでもらい開いて以降調子が悪くなったように思います。
以下のエラーが出てから、 Scene Viewが動かなくなったり等Unityの機能が使えなくなりました。
どうすれば修正できるでしょうか？

■■な機能を実装中に以下のエラーメッセージが発生しました。
