    Using virtual_type

    Once Verify the core file of di.xml arguments passing

    ..../modulename/extensionmodule/etc/frontend/di.xml

     <virtualType name="categoryFilterList" type="ModuleNameExtensionModuleModelLayerFilterList">
    <arguments>
    Your Passing Arguments(same as existing core file - di.xml(core module) passing arguments ).

    </arguments>
</virtualType>

    ..../modulename/extensionmodule/ModelLayer

    <?php

    namespace ModuleNameExtensionModuleModelLayer;
    
    /**
     * Override FilterList Class
     */
    class FilterList extends MagentoCatalogModelLayerFilterList
    {
        ......Your Code Here......
    }
    ?>

    You cannot override the class by plugin. If you want to override the class then just use the following code in your di.xml

    <preference for="MagentoCatalogModelLayerFilterList" type="NAMESPACEYOUR_MODULEModelLayerFilterList" />

    If this not works then goto the parent class (MagentoCatalogModelLayerFilterList) and check the no of arugments you are sending from __contruct function of your module’s FilterList.php. Pass same number of arguments with same order to your parent class. It will work.

    Here is full code to Override MagentoCatalogModelLayerFilterList this class

    I can use virtualType method for override instead of preference

    registration.php

    <?php
MagentoFrameworkComponentComponentRegistrar::register(
    MagentoFrameworkComponentComponentRegistrar::MODULE,
    'Pradip_LayerModel',
    __DIR__
);

    etc/module.xml

    <?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
    <module name="Pradip_LayerModel" setup_version="0.1.0"/>        
</config>

    etc/frontend/di.xml

    <?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">

    <virtualType name="categoryFilterList" type="PradipLayerModelModelLayerFilterList">
        <arguments>
            <argument name="filterableAttributes" xsi:type="object">MagentoCatalogModelLayerCategoryFilterableAttributeList</argument>
        </arguments>
    </virtualType>    
</config>

    Model/Layer/FilterList.php

    <?php

    namespace PradipLayerModelModelLayer;

    /**
     * Override FilterList Class
     */
    class FilterList extends MagentoCatalogModelLayerFilterList
    {
        public function getFilters(MagentoCatalogModelLayer $layer)
        {
            //echo "you can write code changes here"; exit;
            if (!count($this->filters)) {
                $this->filters = [
                    $this->objectManager->create($this->filterTypes[self::CATEGORY_FILTER], ['layer' => $layer]),
                ];
                foreach ($this->filterableAttributes->getList() as $attribute) {
                    $this->filters[] = $this->createAttributeFilter($attribute, $layer);
                }
            }
            return $this->filters;
        }
    }
