Transactions queued indefinitely

Hi,
Example TxId: 0cace654-8f18-47ea-9fee-f729106dc555

In my sandbox account I always get queued transactions that never execute for certain accounts. I have checked all the current transactions and there are no previously executing transactions for this account. Cancelling the transaction and reexecuting doesn’t help.

It seems to happen after I get a smart contract error for an execution with a certain account.
Can you help please.

Thanks

Hi Finone,
My name is Mohammed, and I am with Fireblocks.
The transaction failed due to insufficient funds

The requested fee (7653883276843336) is higher than the current balance (2613857509377130) for 0cace654-8f18-47ea-9fee-f729106dc555.

Thanks
