Are there any alternative rather than Electrum wallet.
Any wallet which allows you to import raw private keys would suffice. Although I agree Electrum is the best and safest wallet for this task, my go-to secondary piece of light wallet software is Sparrow wallet, which would also be able to import from a paper wallet no problem.
If you are going to use Electrum, note that you'll need to prefix your private key with
p2wpkh: if your paper wallet has generated a segwit (bc1q) address.
