After multiple tests, I can confirm that the issue happens only after packing the script into an exe. I used the below commands to pack the perl into exe. Can anyone help please?

Updated code:

 
#!/usr/bin/perl
use strict;
use warnings;
use lib "C:\\Users\\magesh\\SF\\Personal Folders\\Material master\\Mat
+erial_Master_Prod\\Test";
use plmconst ':constants';
use plm_sap_material_master_constant_definitions ':constants';
use Email::Stuffer;
use Email::Sender::Transport::SMTP;
use Email::MIME            ();
use Email::MIME::Creator   ();
use Email::Sender::Simple  ();
use Email::Sender::Role::CommonSending;
use Email::Sender;
use Email::MIME::Header::AddressList;
use Throwable;
use Throwable::Error;
use StackTrace::Auto;
use IO::All;


my $msg_body .= "Hello this is test email";
Email::Stuffer
    ->html_body($msg_body)
    ->subject('Hello')
    ->from(SENDER_EMAIL)
    ->to('mzkuma@abc.com')
    ->transport(Email::Sender::Transport::SMTP->new
        ({
           host => MAIL_SERVER,
           port => MAIL_SERVER_PORT,
        }))
    ->send;

To pack the above test.pl into exe, used below command

 pp -o test.exe test.pl

Also tried

 pp -u -o test.exe test.pl

Any leads would greatly help me. Thank you!
