问题
I found a bug in the latest version of VS Community (16.7.0) which is preventing my solution from building, so I need to roll back to 16.6.5. However the only download link I can find has downloads for only Enterprise and Professional, not Community. How do I downgrade my installation of VS Community? It's completely unusable for me now because one of my solutions is failing to build even though there are no compile errors.

While the link shows Professional and Enterprise, I've tried it myself and it can install the Community version.
First fully uninstall Visual Studio 2019. Then download the Professional edition of the version you want and run it. In the "available" tab from the installer you'll find that it can install all 3 editions including Community of both 2017 and 2019, at the choosen version, regardless of the downloaded binary.
Note that this actually downloads the real installers from the web, thus while they work right now, we can't ensure they'll work in the future.
