Starmaker Account Recovery Without Email or Phone Number

I have been unable to access my Starmaker account for more than a year because of Google account security verification, and I am requesting your assistance in resolving this. I originally created the account on my Vivo Y91 about four years ago, but I no longer remember the answers to the security questions, and I also cannot recall which email address or Google account I used at that time. I do not use the original phone number linked to that account anymore either. Because of these missing details, I am stuck in the security verification steps and cannot open or use my Starmaker account at all. I have not been able to find any alternative way to verify my identity and recover access, and I have not yet received any support since I did not know how to proceed. I kindly request that you provide me with a way to verify and recover my account through alternative methods, such as confirming my identity with any available usage data or other checks that you can apply. I would like to regain access to my Starmaker account that is tied to this old Google account, or be given a clear solution on how to proceed in this situation where I no longer remember the security information.
