TypeError: Object(...) is not a function at eval (platform.es5.js:79) at eval (platform.es5.js:81)

You can't use @angular/material and @angular/cdk version 6.1.0 since your angular dependencies is still at 5.2.0

download the version 5.2.0

npm install @angular/[email protected]

And also keep your angular dependencies on a same version, your @angular/animations is at 5.2.11 where it should be 5.2.0

I had a similar error message, which appears to be caused by version 8 modules being used with Angular 7. The solution for me was to go through package.json looking for version 8 modules (in my case, @angular/cdk and @angular/material), changing them to the most recent version 7 modules, and then re-running npm i

Make sure "@angular/animations" , "@angular/cdk" and "@angular/material" are in same version .Remove ^ symbole and save package.json . At last do npm install .It will solve the issue.
