Hi @gilfoyle2021asc. I can't help but notice that you are in the "mainnet" network. Are you using the random keys generated by the account.GetRandomKeys() function? These keys should be used for testing purposes only, it's not safe to send real funds to these addresses.

Now about the "Account validation failed" error you are facing. This usually occurs when the precomputed address wasn't funded with ETH to pay for the transaction, as the logs say:

The 'precomputedAddress' account needs to have enough ETH to perform a transaction. Use the starknet faucet to send ETH to your 'precomputedAddress' When your account has been funded by the faucet, press any key, then 'enter' to continue :

Did you send ETH to the precomputedAddress generated by the starknet-go?
