Can’t Login to our website WordPress admin after it’s published.

We can’t login to our Ctrify AI created website https://www.jagcouturelondon.com WordPress admin, after it was published. We have used the same username and password we used to create and install the wordpress for this website, but we keep getting error message that the wordpress account does not exist? Please, can you kindly help us to log back in to the wordpress account for this website, so that we can continue our work on the website.
