It looks like you've created a transaction that you no longer control. "If this happens, the transaction will not be confirmed."
Is your balance correct after syncing? No coins lost.
During synchronization, are you sure that unspent output is under your control? In the sense that you did not send? If so, you won't have to worry about syncing.

It is like "spent, sent"
Balance is not correct, I sent all of bitcoins to different wallet, but transaction is not available, it shows up in the screen, but it writes 0 confirms and not available in blockchain.com
