あるはずなのに、Target class [〇〇Controller] does not exist.と出てしまう

Twitterのように、ユーザーをフォローする機能を作成しています。
ユーザーがユーザーをフォローするところで、該当のControllerを作ってはいるのですが、

Target class [UserFollowController] does not exist.

と出てしまいます。
どこかが間違っているとは思うのですが、どう考えてもわかりません……
以下コードです。アドバイスいただけますと幸いです。
(Laravel 8.4を利用しております。)

【状況】
/users/1 （userのid=1のページで、Followボタンをクリックすると）・・・

以下のエラーが出ます。

■view users/{id}

<div class="row">
        <aside class="col-sm-4">
