order confirmation email send twice for customer

[mvp_admin]

When placing an order the customer receives two duplicate confirmation emails.

I found this solution: New order email being sent twice

but I can't find anything in the database !!

I don't know what may be causing the problem or how to fix it. HELP!

Magento ver. 2.2.11
