Here's a somewhat different description of the situation, which I found useful:
"[A] priest convicted of sexual abuse of minors was allowed to stay at an Augustinian priory near an elementary school and continue functions as a priest until later removed, and then laicized in 2012. However, Prevost is said to have never authorized that particular situation, the priest was not an Augustinian, and it took place before the Dallas Charter."

Edit:
There is also this discussion of an incident in Peru:
"More recently, questions were raised about Prevost’s knowledge and handling of abuse allegations in his former Diocese of Chiclayo. Two priests were accused of molesting three young girls, with the allegations surfacing in April 2022 during Prevost’s tenure as bishop. The case has been a source of frustration for local Catholics due to its slow progress and unclear resolution.
"Some accusers have claimed Prevost failed to properly investigate the allegations and covered up for the accused priest, but the diocese has firmly denied this, stating that Prevost followed proper procedures. They stated that Prevost personally received and attended to the victims, and reportedly opened an initial canonical investigation. He also encouraged the victims to take the case to the civil authorities. In July 2022, Prevost sent the results of the investigation to the Dicastery for the Doctrine of the Faith (DDF) for review. His supporters stress that he has documents from the DDF and the Papal Nunciature in Peru which also indicate that he was not only attentive to the presumed victims, but that he did all required in Church law in following procedures set out for these cases.4
"However, in May 2025 allegations emerged that the diocese paid $150,000 to the three girls to silence them. Described as “longtime public critics of Prevost,” the girls reportedly blame Prevost for covering up their sexual abuse by the priest.
"The allegations, reported in InfoVaticana, described the Peruvian scandal, which was the subject of a national television report including an interview with the girls last fall, as the “stone in the shoe for Cardinal Prevost.”
