I have taken another crack at it, and ended up succeding.
I followed this guide: https://walletsrecovery.org/recovery-docs/bitcoinwallet-recovery.html
BUT i cloned and older repository, i choose release 0.11 as it came out in 2014 and i saw my backup was from 2013.
It is now succesfully syncing.
According to https://github.com/bitpay/copay
Copay wallet is now Bitpay Wallet. Repo at https://github.com/bitpay/wallet
So you shouldn't be using the Copay app.
it also says
WE HAVE DETECTED SOME FAKE COPAY WALLETS ON THE GOOGLE PLAY STORE FOR ANDROID THAT WILL STEAL YOUR COINS
So you need to be certain you have a genuine non-malicious app.
If you have ...
You can accomplish all of this and more using a "pay to script hash". You can even do more complicated rules like "let my business partner have access to my account if either my lawyer or my wife agrees (but lawyer and wife can not together access account, so more complicated than just 2-of-3)."
Here is a great chapter on this stuff...
If you are using Bitcoin Core:
1 - Go to window > console
2 - Type listunspent
3 - You will get a list of addresses with the spendable amount
4 - Copy one of those addresses
5 - Type dumpprivkey pasteYourAddressHere
It seems you have a BIP38 encrypted Private Key, you cloud try:
1 - go to https://www.bitaddress.org/
2 - go to "Wallet Details"
3 - paste the text you have in "Enter Private Key"
4 - click on "View Details"
5 - paste your 12 characters pass in "Enter BIP38 Passphrase"
6 - click on "Decrypt BIP38"
