Docker Desktop 3.0.4 (v20.10.2 engine) no longer works with VS2019

Recently I updated Docker Desktop and VS2019 no longer sees it as installed. This means I am no longer able to add Docker support when creating a new web api (it will add all the plumbing in with the Dockerfile and adding the VSTools). Web Api is a net Core 3.1 web app. VS 2019 v16.8.3

Note that I also have at least 6 other web apis which all have Docker support already in them (all on net Core 3.1) which until I updated all built and ran in the local Docker.
