I’m going to keep this alive because of the discussion, but this is a duplicate of https://github.com/angular/angular-cli/issues/8107 and will be closed as such when we find a solution.

Seems to be another duplicate of the issue with multiple TypeScript versions in the project. See https://github.com/angular/angular-cli/issues/5053, https://github.com/angular/angular-cli/issues/8107, https://github.com/angular/angular-cli/issues/8174.

You goal should be to ensure that your project has single instance of TypeScript package. Linked issues describe some workarounds how to achieve it.
