Uncaught (in promise): Error: Angular JIT compilation failed: '@angular/compiler' not loaded!...

I create a webaite with angular 9 but i have a problem with angular .

In some route I have the error:

ERROR Error: Uncaught (in promise): Error: Angular JIT compilation failed: '@angular/compiler' not loaded!
- JIT compilation is discouraged for production use-cases! Consider AOT mode instead.
- Did you bootstrap using '@angular/platform-browser-dynamic' or '@angular/platform-server'?
- Alternatively provide the compiler with 'import "@angular/compiler";' before bootstrapping.

But in some routes I do not have this error. Another weird thing is that in local it works fine but in server it did not work. What's the problem and how can I solve it?

In my server I place the put the files in the app folder, while in the local machine I don't have this folder.

Here is angular.json:
