1031 exchange converted to primary

[Kareena Sharma]

Hi,

This question is for a friend's mom. She completed 1031 exchange and converted 1031 property into primary residence, almost immediately after 1031 (one month). I know the rules that she should have used the property as rental for 2 years and then moved in. However, she moved in for some reasons. property was purchased in Dec 2021 and moved in Jan 2022. 

Question: would this invalidate the 1031 exchange ? If yes, would she require to pay capital gains in 2021 or 2022?
