There are several issues here. It doesn't matter what year it is, so 2024 is irrelevant. It's actually 1403. Regarding wali (guardian), a woman doesn't have to have one. Independent women do not require a guardian. Many woman have a wali, and many don't. Your wali is/was your father or grandfather until you became independent. You don't need a wali to talk to someone. If you want to get married, you should ask your wali's blessing, but if he refuses you can still get married.
