There is Question mark on the left (?) Status: 0/unconfirmed not in memory pool. Color: grey

Since it's not in your memory pool, you should have an option to abandon that transaction in the right-click menu.

In my previous post, I've mentioned a way to check for the details of that transaction in the console, you might want to check it before deciding to abandon the txn.

It doesn't look like the transaction you've linked in the OP because of the total fee and size. A transaction conflict ('cause of RBF/etc.) maybe?
You can check the outputs and other info before deciding to send/abandon the txn using the command decoderawtransaction "RAW_TXN" to view its human-readable format.

Since he's using the GUI, he can simply right-click on it and select "Copy raw transaction" to get the signed RAW Txn or follow what's written in the error.
