Recovery Requested for Snapchat Account denizkarci47 Without Linked Email Details

I have been unable to log into my long-used Snapchat account for about 1 month. Although I enter my username (denizkarci47) correctly on the login screen, I cannot complete the password reset steps because I forgot my password. Since I do not remember the Gmail address or the registered phone number I used when opening the account, I cannot perform the password reset process through the system.

I have important memories, photos, and my friend list in my account, and I want to regain access to this account. I demand that Snapchat assist me in restoring my account for use through my username or another method such as identity verification, and provide a solution regarding password renewal.
