Howdy! I've tried everything to get this up to date, including attempting the docker container, as well as downloading trasherdk/phpvirtualbox 6.1 source code.

You probably need to download the latest phpVirtualBox 6.1-x. See the Versioning section below the file list in the link for more information" I believe...
