I just downloaded and installed Papyrus Oxygen. I wanted to give the Papyrus Alf Editor a new try, but unfortunately, I was not able to install the plugin. Are there any known issues that prevent installation of Alf Editor in Papyrus Oxygen?

There seems to be some problem with this particular item in the installer. It seems there are some conflicts on the plugin versions already installed if you already have papyrus so this may come down to a "simple" rebuild of the repository.
You can still install the associated feature from here  but you will encounter the same problem. I will keep you updated as soon as this is resolved. (note that, although this is not ideal, you can still install alf through  and then papyrus on top of it) this results in a very strange/uncomplete installation so I would not recommend it.
