Legal name change - W2 incorrect

My adult child received a legal name change in 2022 and updated their birth certificate, state ID and also social security card.  Their employer processed the 2022 W2 with the previous name rather than the updated name. 

Can taxes be filed with the incorrect W2 if the names don't match?  (The last name did not change, only first and middle.)

Is it a requirement that the employer provide a corrected W2?
