        'password' => 'required|same:confirm-password'
    ]);


    $input = $request->all();
    $input['password'] = Hash::make($input['password']);

In line 147 of this file vendor\egulias\email-validator\EmailValidator\Parser\Parser.php

Change it from this if ($previous['type'] === EmailLexer::S_BACKSLASH

To this if (isset($previous['type']) && $previous['type'] === EmailLexer::S_BACKSLASH ...

I was facing the same problem, after debugging I found my smtp credentials was not working properly, email sending modules was not working that why I was getting this error, after fixing the credentials my code starts working properly and exception get disappear.

I suggest you to check your smtp credentials and make your you turn on less secure app setting.
