Based on the given information, it appears that the balance has not gone anywhere. The operation referenced in the question appears to be an injected operation, meaning that it was never included in a block and therefore never processed. This means that the balance has not changed, and the funds are still in the account.

So it's mean the balance gone ?

This just looks like an injected operation that never went through. e.g. never included in a block.
