Telegram Recovery Email Disappeared and I Lost Access to My Account

I have been using a Telegram account registered with the mobile number +91 76800069**  on my Android phone. Today I logged out of my account, and when I tried to log in again, I was unexpectedly asked for two-step verification, even though I clearly remember that I did not enable this option when I created my account. In addition, the system shows that there is no recovery Gmail linked to my account, although I had definitely added a recovery email. I am also sure that I remember my password correctly, but Telegram keeps showing that the password is wrong, so I cannot access my account at all. I contacted Telegram support about this issue but have not yet received any response. I also tried uninstalling and reinstalling the app and logging in again, but the problem continues. When I click on “Forgot password”, the only option I see is to reset the account, which would lead to losing my existing data and chats. I request your support to help me recover access to my Telegram account at the number +91 76800069** without resetting or deleting my data. I kindly ask you to disable or correct the two-step verification that I did not activate, recognize my recovery email if possible, and assist me in logging back into my existing account.
