I cannot import a theme in wordpress on IIS

Question

Wordpress 6.0.1 is installed on IIS with PHP 7.4.30 and I'm using a plugin named All-In-One WP Migration to import a theme created on the same version but installed on XAMPP.

I want to move my wordpress theme created on XAMPP (PHP 7.4.29) to a IIS server (PHP 7.4.30), MySQL will stay on XAMPP.

I'm using a plugin called All-In-One WP Migration to export the theme but when I want to import it doesn't work, it stays at 100% and in the browser console I see error 413 (Request Entity Too Large).

If I import the theme on another XAMPP server this process of import works fine.

The reason I want to use IIS is because I have another asp.net website on it.

Screenshot :

web.config :

<?xml version="1.0" encoding="UTF-8"?>

                    <conditions logicalGrouping="MatchAll" trackAllCaptures="false">
                        <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
                        <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
                    </conditions>
                    <action type="Rewrite" url="index.php" />
                </rule>
            </rules>
            <outboundRules>
                <clear />
            </outboundRules>
        </rewrite>
    </system.webServer>
</configuration>

In php.ini I have configured these two values :

upload_max_filesize = 2000M
post_max_size = 2000M

I solved it by installing an older version of the plugin, link :
