bug: deployment simulation returns empty data

[enitrat]

safe-global team wants to deploy singleton factory, however, the simulation returns empty bytecode (which means if it is deployed wrongly - it can not be undone as nonce has been already used and contract address won't be usable as there is no code).
Here is a contract deployment data:

curl -s https://sepolia-rpc.kakarot.org/ -H 'content-type: application/json' --data '{"jsonrpc":"2.0","id":0,"method":"eth_call","params":[{"data":"0x604580600e600039806000f350fe7fffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffe03601600081602082378035828234f58015156039578182fd5b8082525050506014600cf3"},"latest"]}'

There were similar issues for other networks (etherlink and swisstronik), maybe those discussions will also be helpful:
safe-global/safe-singleton-factory#678
safe-global/safe-singleton-factory#545

Edit*
To add how they simulate: (call example)

1. simulate the contract deployment (e.g. try to use their signer -> call with deployment data)
2. check if get_Code returns result (if it is not 0x - then it would be deployed well)
3. but if it does return 0x - then something reverted, was wrong and contract was not deployed BUT transaction would be pushed, nonce used and other singleton will have a different address - which in this case is unfavorable.

we need to check why this is not returning the right data.
