IE11 empty page using Angular 7

I'm testing my personal website from host. It works fine with chrome, safari, firefox, almost fine with edge, and not at all with IE11. The page displayed is index.html, the scripts don't load and so, my page is desperately white. What direction should I look at?

Below is the source code after loading, it just renders the index.html

<!doctype html>
<html lang="fr">
<head>
  <meta charset="utf-8">
  <title>xxxxx</title>
  <base href="/">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="icon" type="image/x-icon" href="favicon.ico">
  <link href="https://fonts.googleapis.com/css?family=Open+Sans:300, 400|Permanent+Marker|Fredoka+One" rel="stylesheet">
  <link rel="stylesheet" href="https://use.fontawesome.com/releases/v5.7.2/css/all.css" integrity="sha384-fnmOCqbTlWIlj8LyTjo7mOUStjsKC4pOpQbqyi7RrhN7udi9RwhKkMHpvLbHG9Sr" crossorigin="anonymous">

<link rel="stylesheet" href="styles.e51f265321605de0a6b8.css"></head>
<body>
  <app-root></app-root>
  <script type="text/javascript" src="polyfills.46532d96d3286697c138.js">

<script type="text/javascript" src="runtime.a5dd35324ddfd942bef1.js"></script><script type="text/javascript" src="main.d7a4eeb20e2af3af291c.js"></script>
</body>
        </html>

Solution

polyfills.ts
