In Japanese, the verb やり直す is frequently used in the phrase 人生をやり直す, which translates to 'to redo one's life'. This concept is a central theme in the popular 'Isekai' genre of anime and manga, where characters are often reborn to fix past mistakes.
The verb やり直す is a combination of the verb 'yaru' meaning 'to do' and 'naosu' meaning 'to fix' or 'to repair'.
Using やり直す when you actually mean 'repeat' can accidentally offend someone by implying their first attempt was a failure that needed fixing.

最初からやり直す。

このレポートはやり直す必要があります。
Kono repōto wa yarinaosu hitsuyō ga arimasu.
