But the first of January 2023 was a Sunday; according to the ISO standard it was part of the 52nd week of 2022.
The problem is that we really like to display calendars as Sunday through Saturday, but the ISO standard considers Thursday to be the all-important day of the week.
This Mac calendar behavior would be a bug (probably) if it was claiming that the week number it was displaying was the ISO 8601 week number; I'm not even sure how you could possibly find a way to print a single week number per week in a Sunday-through-Saturday calendar according to ISO 8601. That's just not the use case.

End of pedantry. see also https://qntm.org/calendar https://qntm.org/calendar : ( ) the lunar month cannot be evenly divided into seven-day weeks ( ) the solar year cannot be evenly divided into seven-day weeks ( ) having one or two days per year with no day of the week is asinine
