上記の解決策を試しましたが、うまくいきませんでした。私は私のために働いた次のことをしました

ng update --next @angular/cli --force
npm install TypeScript@latest

私はこの問題を抱えており、プロバイダーをモジュールに追加することによってのみ解決できました

import { ɵMatchMedia, BreakPointRegistry, PrintHook } from '@angular/flex-layout/core';                
import { FlexLayoutModule, StyleUtils, StylesheetMap, LayoutStyleBuilder, MediaMarshaller, LayoutAlignStyleBuilder, FlexStyleBuilder } from '@angular/flex-layout';


 providers:[
    PrintHook,
    StyleUtils, 
    StyleSheet,
    StylesheetMap, 
    LayoutAlignStyleBuilder,
    LayoutStyleBuilder,
    FlexStyleBuilder,
    MediaMarshaller,
    ɵMatchMedia,
    BreakPointRegistry],
