Permission Issue for laravel APP QUEUE in windows server 2012 - windows

Question

We have a laravel app (Version 5.5*) deployed in WIndows Server 2012 R2. But our development stack is LEMP. Same codebase works fine in development STACK but fails in WINDOWS SERVER.
Problem:
In our App, there is a REPORT DOWNLOAD queueable job which reads data from database table and generates an excel file using box/spout package(version 2.7) depending on user input date range (daily,weekly,monthly, etc) .
When running the queue:work command from cmd as administrator,
$writer->openToFile(‘path/to/file’) throws an error : failed to open stream : no such file or directory.
See this image for code snippet throwing error
Solutions I tried:
Setting right permissions(full control Read & write) for Storage folder of my project (For Users, IIS_IUSRS,IUSR)
Setting right permissions(full control Read & write) for C:windows\Temp folder (For Users, IIS_IUSRS,IUSR)
Created symlink for storage folder inside public
FYI:
OS: windows server 2012 r2
PHP: 7.2*
Laravel: 5.5.*
box/Spout package: 2.7.*

You can follow the following procedure:
Go to IIS Manager
Select your desired project (For example: myexampledomain.com) listed under Sites
Go to Security tab and you'll see the users listed with their permissions on the folder.
Now, click Edit button to go to a new window and click Add. In the text box,type IIS AppPool\MyApplicationPoolName.In our example it should be IIS AppPool\myexampledomain.com.
Click Check Name and you'll see the test change with underline.
Click Ok. Add the appropriate permission(Modify,read,write) to the newly created user.
That's it!!!
Thanks to all for responding.
