If the wallet (like the puzzle 64) is empty you cannot sign new transactions. Zero bitcoin means zero transactions available.

Here you can find an archive of private keys, all empty wallets :
https://privatekeys.pw/keys/bitcoin/3If you are lucky and you find a privkey with bitcoins inside you can use a wallet like Exodus (there are tutorials online how to importing a paper wallet).

i tried to use electrum on that found private key, but electrum doesn't recognise the format of that private key.
how we use found private key? is there any other process to change format of the private key so it can be use on electrum or any wallet?
