unstake pepeunchained layer 2 coins

There is a website tied to this crypto, it's an Ethereum Layer 2 coin. Everything works, except…. unstaking staked coins. In their Telegram group, they claim it's a bug and will be fixed soon. It's been days. People also say, that it's a website bug, not a blockchain bug…. So it should be possible to unstake somehow, right? I would expect the devs to (first of all apologize) give us a manual solution until they fix this, but all they say is "it will be fixed soon" followed by "why would you wanna unstake in the first place?"…. Well, I was gonna hold this for a while, I was just testing if this even works, assuming that it does….. but now I kinda wanna get out of this. Can someone with Ethereum knowledge figure out what I need to do to get my coins back?

For the record, I already made profit with this, this is just the other half that I didn't cash out yet.

If there is a good solution, I will share it with people in the Telegram group that ask about this.
