ESocial - Event signature invalid. Suggested Actions: Check if event has changed after signing. Verify signature validity

I am trying to send the evtInfoEmpregador event and when querying the batch return is returning the message.

<tipo>1</tipo>
<codigo>142</codigo>
<descricao>Assinatura do evento inválida. Ações Sugeridas: Verificar se houve alteração do evento após a assinatura. Verificar a validade da assinatura.</descricao>
 <localizacao>/eSocial/Signature</localizacao>

I am generating the event, signing and including in the batch, however, after signing, I make an XElement.Parse, because the signature method returns a string.

Follow sent / signed XML, hiding only the data of the signature and CNPJ.

Does anyone know what might be happening?
