Long story short, I've been using GUARDA multi-signature BTC Wallet (2 of 2) with me and my friend to store some BTC. There's been a bug since December; where if you broadcast a transaction, the co-signer cannot see it, hence cannot sign/broadcast it, leaving your crypto in limbo. Guarda are aware of the bug and are fixing it. However, I do not have the time to wait for them to fix it as it has been 2 months and I need access to it urgently due to upcoming costs and bills.

So here is where I am looking for advice on how to recover the BTC inside the wallet, as I have absolutely no idea what to do, or where to start, and since its a multi-signature wallet its a lot more complex than a normal recovery.

We both have access to the "private key" of the wallet. But I have a few questions:

1. If I am able to recover the BTC with just MY private key to the wallet, does that not defeat the purpose of the multi-signature system? As that would mean I can just import my private key and recover our shared BTC from my co-signer just by myself?

2. I may have understood incorrectly, but would me and my friend have the same private key as it's a multi-signature wallet, or would they be different? And if they are different, how would we actually recover the crypto from our Guarda Wallet and put it onto another wallet?

Thanks for the help guys. I WILL tip for actual help that helps me recover my crypto onto another platform step-by-step.

FYI: I'm not on the spectrum, so please don't try to send any DMs/scams. Ty.
