Answer 1

For me a reinstall with the latest versions helped:

npm remove @angular/material @angular/cdk
npm i @angular/material@latest @angular/cdk@latest

Replace npm with yarn in case you have yarn.

Answer 2

Add this to tsconfig.json:

{
  "compilerOptions": {
    "skipLibCheck": true
  }
}

If you have npm version 8, try downgrading to an older version. It fixed the problem for me.
