Question Can't use the version I just updated to

I was using a 2020 version, and I believe it's broken in the way that it doesn't show serialized arrays in the inspector. So I went through the whole annoying process of downloading the newest stable version (2021.3.19f1, a commenter was correct about the version), released just over a week ago or so. I go through the whole process, and restart my computer, and the version is NOT in the Unity, either to open an old project with, or to use for a new project. I did update the Unity Hub prior to updating Unity itself.
How do I actually use the new version I just got? I'm sure it's user error, but it still feels like something's wrong.

 

I think the 2022 version's still in Beta, the most recent LTS version's the 2021.3.19f1 I think.
