AssociatedTokenAccountsExample Example problem : Blockhash not found

[mortezadalil]

When I change wallet MnemonicWords to new one and run AssociatedTokenAccountsExample , I got this error in response of transaction : Transaction simulation failed: Attempt to debit an account but found no record of a prior credit.

I got this error in this line of code: Examples.SubmitTxSendAndLog(createAndInitializeMintToTx);
