use Illuminate\Contracts\Encryption\DecryptException;
use Illuminate\Support\Facades\Crypt;
use Illuminate\Support\Facades\Cookie;

 
try {
    $decrypted = Crypt::decryptString(Cookie::get('cookie_name'));
} catch (DecryptException $e) {
    // ...
}

By default Crypt::decrypt tries to deserialize the value, and yours is not serialized and that's why you get the error. You need to pass a second argument like:

Crypt::decrypt(Cookie::get('userId'), false);

In web request context cookies are usually automatically encrypted and decrypted by the EncryptCookies middleware. So easiest option would be just to enable this middleware (and it's enabled by default in Laravel).

If you need to decrypt any value manually, the following will do the trick:

// get the encrypter service
$encrypter = app(\Illuminate\Contracts\Encryption\Encrypter::class);

// decrypt
$decryptedString = $encrypter->decrypt($encryptedString);

Check the code of the EncryptCookies middleware to learn more about what it does internally.
