Twitch entered wrong email address?

I'm very desperate at the moment. I found my old twitch account and wanted to change the email address. Everything worked, but I realized that I made a mistake in my email entry. When I entered the email as usual, I left myself behind and the email address already existed, of course I wanted to change it again, but the confirmation code goes to the stranger and without it I can't change the email, although I already have the person with me the email was written to but she did not answer

Are there other ways

If the verification code is never entered, the address will never be changed. So you should be able to enter a new, this time correct, address.
