ngx-translate with Angular 9 not working in IE

Question

Our App don't work in the IE, it's showing only a compilation error (SCRIPT1002) and when navigate to that line it shows the class TranslateLoader.

I have already found a similar question about this, unfortunately the answer doesn't work: ngx-translate with Angular 9 not working in IE showing compilation error SCRIPT1002

Any help would be great. Many thanks.

I found a similar thread and I followed the solution in it then it can work well in IE 11. I use ngx-translate like this simple sample. You could refer to my files:

package.json

...
  "dependencies": {
    "@angular/animations": "~9.1.0",
    "@angular/common": "~9.1.0",
    "@angular/compiler": "~9.1.0",
    "@angular/core": "~9.1.0",
    "@angular/forms": "~9.1.0",
    "@angular/platform-browser": "~9.1.0",
    "@angular/platform-browser-dynamic": "~9.1.0",
    "@angular/router": "~9.1.0",
    "@ngx-translate/core": "^11.0.1",
    "@ngx-translate/http-loader": "^4.0.0",
    "classlist.js": "^1.1.20150312",
    "rxjs": "~6.5.4",
    "tslib": "^1.10.0",
    "web-animations-js": "^2.3.2",
    "zone.js": "~0.10.2"
  },
...     

tsconfig.json

{
  "compileOnSave": false,
  "compilerOptions": {
    "baseUrl": "./",
    "outDir": "./dist/out-tsc",
    "sourceMap": true,
    "declaration": false,
    "downlevelIteration": true,
    "experimentalDecorators": true,
    "module": "esnext",
    "moduleResolution": "node",
    "importHelpers": true,
    "target": "es5",
    "lib": [
      "es2018",
      "dom"
    ]
  },
  "angularCompilerOptions": {
    "fullTemplateTypeCheck": true,
    "strictInjectionParameters": true
  }
}

The result in IE 11 is like this:
