Why can't I unstake my ETH?

I've been wondering, why can't I unstake my ETH? I've followed all the steps, but the option just isn't there. Could it be a technical glitch? Or is there some rule or policy I'm not aware of? It's frustrating because I need to access my funds. Could you please clarify what's going on? Maybe there's a specific timeline I need to follow, or a certain condition that hasn't been met. I'd really appreciate your help in understanding this. After all, staking was supposed to be a way to earn passive income, not a hindrance to accessing my own money.
