TikTok No Password, No Email Help!

I opened a TikTok account around 2021 with the username @strawb3rymilkshake, but I can no longer access it because I forgot both the password and the email address linked to the account. The account is not connected to any other login method, so I am completely locked out. I contacted TikTok support and provided the evidence of ownership they requested. Despite this, I was told to contact the email associated with the account, which I do not remember and cannot access. This puts me in a dead end, even though I have already proved that I am the owner of the account. I kindly request that my account be recovered and that I be given an alternative way to verify my identity and change the login information, instead of being directed to an email address that I no longer have access to. I would like to regain access to this account as soon as possible.
