send email messaage with attachment by batch file

Question

Hi i'm trying to send email from batch file.bat but I'm getting a list of red errors and rolling really fast and the window close also fast I tried to keep it open by the command

cmd /k

and it's still open but it won't show any error list.

not that: I'm using Gmail account as smtp and i opened smtp settings and enabled the less secure login option.

finally what to run the bat is that command. cmd execute command :

file.bat "mygmail@gmail.com" "mypassword" "D:\test\myFile.txt"

file.bat contains :

@ECHO OFF
    SET GmailAccount=%~1
    SET GmailPassword=%~2
    SET Attachment=%~3

    CALL :PowerShell
    CD /D "%PowerShellDir%"
    Powershell -ExecutionPolicy Bypass -Command "& '%PSScript%' '%GmailAccount%' '%GmailPassword%' '%Attachment%'"
    EXIT

    :PowerShell
    SET PowerShellDir=C:\Windows\System32\WindowsPowerShell\v1.0
    SET PSScript=%temp%\~tmpSendeMail.ps1
    IF EXIST "%PSScript%" DEL /Q /F "%PSScript%"

    ECHO $Username      = $args[0]>> "%PSScript%"
    ECHO $EmailPassword = $args[1]>> "%PSScript%"
    ECHO $Attachment    = $args[2]>> "%PSScript%"
    ECHO                          >> "%PSScript%"
