If funds transferred to another unknown wallet without any action from your side mean your seed phrase or private keys have been compromised somehow. May be you have downloaded electrum from fake source or may be you have created paper wallet from fake or phishing sources. Sorry to say but it won't reverse anymore.
The day before yesterday, my wallet with physical cash was stolen, and today - the rest of my hope was cleared.
Are you sure your private key were not written on your physical wallet ? If so, then likely same guy steal your fund. Anyway don't be hopeless, somehow you will be out of this problems. Try to manage fund from offline.
