Do you see the reviews next to it? Not quite unwarranted. It's notoriously bad at times. Your only hope is, to go back and install older versions of the language service. There are many esoteric suggestions in comments, blogs, and so forth, but they never were the solution.
After you select that, try to pick a corresponding version to your currently running Angular version and try out different versions.
I guess visual studio code did not accept the update because the version is old. I deleted and re-downloaded it.
