When creating a new multi-sig wallet, make sure to use the Master Public key that you previously used so you can reaccess the wallet address on the multi-sig wallet you created.
Did you mean master private key?It is not 2-of-3 multisig wallet, neither the number of signature needed are more than the number of cosigners. To recover 2-of-2 multisig wallet, everything needed are the two seed phrases, master private keys or private keys.
Master Public key, if you use a multi-sig wallet such as Electrum + hardware wallet because the hardware wallet already represents the master key or seed phrase.
However, if you use a multi-sig wallet on Electrum without selecting the "Use a Hardware Device" option, you need a seed phrase or master key.
Here's an example:

Under wallet type, select Multi-Signature wallet.
Then specify the Consigner and also the number of signatures needed to be able to process transactions in the wallet.
On "Add cosigner (1 of 2)", I selected the option "Use a hardware device".
In 'Hardware Keystore', select the connected device, then clicks 'Next'.
- Device on Wallet (Cosigner) 1:
- Device on Wallet (Cosigner) 2:
Select the wallet address type; For "derivation path", I leave it by default.
Then write the 'Master Public Key' it generates, then clicks 'Next'.
- Master Public Key on Cosigner 1:
- Master Public Key on Cosigner 2:
On the 'Add Cosigner (2 of 2)', select 'Enter cosigner key'.
In wallet 1, fill in using the master public key (xpub) of wallet 2:
In wallet 2, fill in using the master public key (xpub) of wallet 1:
Create a password to encrypt each wallet on both 'Cosigners'.
Go to the 'Addresses' tab (View Menu -> Show Addresses), and make sure the addresses in all Cosigners are the same:
- Address Wallet (cosigner) 1:
- Address Wallet (cosigner) 2:
