Does it cost to unstake Ethereum?

I'm curious about the costs involved in the process of unstaking Ethereum. Do I have to pay any fees to unlock my staked coins? I've heard that staking Ethereum can be quite lucrative, but I'm also aware that crypto transactions often come with a price tag. So, does unstaking Ethereum cost money? If so, how much does it typically cost? And are there any other considerations I should be aware of before deciding to unstake my Ethereum?
