Could not determine the Safe creation parameters

[gionn]

Bug description

Environment

• Browser: Firefox
• Wallet: MetaMask
• Chain: N/A

Steps to reproduce

1. Create a safe wallet on Base
2. Add another network (Optimism) - using gasless/sponsored transaction
3. Add another network

Expected result

It should allow me to create a 3rd safe on any supported network

Obtained result

I get a fatal error immediately after clicking Add another network:

Code 816: Error computing replay Safe creation data (The Safe creation information for this Safe could not be found or is incomplete.)

Screenshots

I managed to create a new safe on Ethereum using the top-right contextual menu after entering the Optimism safe, and now also the issue to add another network from the safe selection page is gone.

So it really looks like that if the first listed safe has been created with a sponsored transaction then the network add feature when initiated from the safe selection page is broken.
