It seems that Ecuador may not participate in the World Cup. According to the Daily Mail, there are quite compromising documents, which again call into question the possibility of being excluded from the World Cup.

In the audio document, allegedly collected in the interview made in 2018, the player can be heard clearly saying that he was born in 1995 and not in 1998 as appears on his Ecuadorian birth certificate, giving his name as Bayron Javier Castillo Segura and not Byron David Castillo Segura.
