fatal error(): Failed opening required "path" (include_path='C:\xampp\php\PEAR') in phpmailer

I am new to PHP and I want to create a web app, which can send an OTP to the user's email. everything is working as expected, when I provide an email to the input and click send OTP, it registers the email to the database and even redirects to the next page where it shows this error:

Warning: require(D:\Suggest_Random_Comic-main<D:>Suggest_Random_Comic-main/vendor/autoload.php): failed to open stream: No such file or directory in D:\Suggest_Random_Comic-main\SendMailConfig.php on line 6

This is the snapshot of the error:

Fatal error: require(): Failed opening required 'D:\Suggest_Random_Comic-main<D:>Suggest_Random_Comic-main/vendor/autoload.php' (include_path='C:\xampp\php\PEAR') in D:\Suggest_Random_Comic-main\SendMailConfig.php on line 6
