IIS and Mautic 5.0.2 Problem

Your software
My Mautic version is:5.0.2
My PHP version is:8.0.30
My Database type and version is:10.6.13-MariaDB

Your problem
My problem is: Internal Server Error-500

I uploaded the mautic software, which I downloaded from GitHub - mautic/mautic: Mautic: Open Source Marketing Automation Software., to the site as a subdomain and added the installation parameters and database connections to the installation page.
But during the first run, it gave a 404 error at /s/dashboard. Thereupon, I prepared my web.config file as follows.

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

but this time “Uh oh! I think I broke it. If I do it again, please report me to the system administrator!” It gives Error-500 error.

What do you recommend me to do in this situation?

I installed
