Why can't I withdraw from my Binance?

Hello there, I'm having some issues with my Binance account. I'm trying to withdraw my funds, but the system keeps denying my requests. Could you help me understand why I'm unable to withdraw from my Binance account? Is it a technical issue, or is there some kind of restriction that I'm not aware of? I'd really appreciate your help in resolving this matter as soon as possible. Thank you.
