I'm trying to load my .phtml files in the template folder within my observer but I'm getting this error

Invalid template file: 'VENDOR_MYModule::Category/index.phtml' in module: 'VENDOR_MYModule' block's name: 'category_0'

Here's the structure of my files

app

 + code

    + VENDOR

      + MYModule

        + Block

            - Category.php

        + Controller

            + Category

               - Index.php

        + etc

            + frontend

                - routes.xml

        + Observer

            - CategoryObserver.php

        + view

            + frontend

                + layout

                    - header_category_index.xml

                + templates

                    + category

                        - index.phtml

Now the content of my Block/Category.php is below

<?php

namespace VENDORMYModuleBlock;



class Category extends MagentoFrameworkViewElementTemplate 

{

    public function __construct(

        MagentoBackendBlockTemplateContext $context,       

        array $data = []

    ){

        parent::__construct($context, $data);

    }



}

The content of my Controller/Category/Index.php is below

<?php

namespace VENDORMYModuleControllerCategory;



class Index extends MagentoFrameworkAppActionAction

{

    protected $_pageFactory;    



    public function __construct(

        MagentoFrameworkAppActionContext $context, 

        MagentoFrameworkViewResultPageFactory $pageFactory

    )

    {

        $this->_pageFactory = $pageFactory;     

        return parent::__construct($context);

    }



    public function execute()

    {       

        return $this->_pageFactory->create();

    }   

}

The content of the layout/header_category_index.xml is below

<?xml version="1.0"?>

<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" layout="1column" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">

    <referenceContainer name="content">

        <block class="VENDORMYModuleBlockCategory" name="category_items" template="VENDOR_MYModule::category/index.phtml" />

    </referenceContainer>

</page>

The content of my .phtml is just a simple <h1>Hello world</h1>. Now in my Observer I'm trying to load this .phtml file but I can't load it and getting the error. The content of my Observer ObserverCategoryObserver is below

public function execute(MagentoFrameworkEventObserver $observer)

{           

    $layout = $this->_layout->create();

    $block = $layout->createBlock('VENDORMYModuleBlockCategory')->setTemplate('VENDOR_MYModule::Category/index.phtml')->toHtml();        



    $this->_logger->debug("[DEBUG]::" , [$block]);

}

Here's the content of my events.xml

<?xml version="1.0"?>

    <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">

    <event name="catalog_category_save_after">

        <observer name="category-edit" instance="VENDORMYModuleObserverCategoryObserver" />

    </event>   

</config>

But I'm getting the error as mentioned above. Any idea on how to load this .phtml file to the observer? I'm planning to write the content of this .phtml file to a .txt file. But I can't proceed since I tried outputting it but I'm still getting an error

Change this line:

    $block = $layout->createBlock('VENDORMYModuleBlockCategory')->setTemplate('VENDOR_MYModule::Category/index.phtml')->toHtml();        

to

    $block = $layout->createBlock('VENDORMYModuleBlockCategory')->setTemplate('VENDOR_MYModule::category/index.phtml')->toHtml();        

[Update]

<?php

namespace SRMagentoCommunityObserver;



use MagentoFrameworkEventObserverInterface;

use MagentoFrameworkEventObserver;



class CatalogCategorySaveAfter implements ObserverInterface

{

    private $layout;



    public function __construct(

        MagentoFrameworkViewLayout $layout

    ) {

        $this->layout = $layout;

    }



    public function execute(Observer $observer)

    {

        $block = $this->layout->createBlock('SRMagentoCommunityBlockCategory')->setTemplate('SR_MagentoCommunity::category/index.phtml')->toHtml();

        error_log($block);

    }

}

Template location:

app/code/SR/MagentoCommunity/view/base/templates/category/index.phtml

$block = $layout->createBlock('VENDORMYModuleBlockCategory')->setTemplate('VENDOR_MYModule::category/index.phtml')->toHtml();
