u can delete the node_modules folder and you can do npm install, everything works perfectly

The same problem with me.

Solution:

  1. delete the project
  2. clone project from your repo
  3. npm install
  4. open vscode and select > setting > Online services setting > settings sync > Edit in settings.json and change "angular.experimental-ivy": true to "angular.experimental-ivy": false

I have the same problem.

I tried to delete node_module and do npm install but it is not fixed.

Then, I finally remove @angular/material from package.json and reinstalled using npm install. It is solved.
