Struggling to Access My ROBLOX Account

I'm experiencing some difficulties accessing my ROBLOX account. Every time I input my password, I am immediately redirected to a screen that is solely dedicated to ensuring my security. It kindly requests me to enter a code that has been sent to my email. Unfortunately, my email is outdated and I am unable to access that account. Could you provide some assistance? I have dedicated a significant amount of time and energy to my account, and I can confidently say that I have not engaged in any improper behavior. I have my password and username, but it seems that my email is not registered. I would greatly appreciate your assistance.
