Verification code sent to outdated email

While attempting to log in to my wordpress site, I received the following notification:

We’ve noticed that your current password may have been compromised in a public leak. To keep your account safe, we’ve added an extra layer of security. We’ve sent a code to e****@c**.et. Please check your inbox and enter the code below to verify it’s really you.

Unfortunately, this is an outdated email address that no longer exists. (I’ve made previous attempts to update it in my account, but run into the same problem – they always send a verification to the nonexistent address.) I cannot access my website to update prices or product information, and I have a huge sales event coming up this weekend. The Jetpack support AI provided me with the following instructions:

Since you no longer have access to that email address, you’ll need to contact our Happiness Engineers for help. They can deactivate the Account Protection module for you.

Please help.

Note: I had to create a new WordPress account to log in to this forum. It is not currently associated with the website in question (assamteas.shop).
