Downgrading/Partitioning Ubuntu

I'm a new Ubuntu user running Ubuntu 20.04 and have been liking it so far. I have reached a dilemma now. I would like to learn Game Development via Unity Hub, a game engine requiring Ubuntu 18.04 or 16.04. I don't want to downgrade because I like this version and many other apps are 20.04 only. I want to know if I need to downgrade to 18.04, and if so, how do I partition both Ubuntu 20.04 and 18.04? I tried running Unity Hub but I can't get past the sign-in page. Thank you for your answers in advance!

Edit: In more detail, I downloaded the Unity Hub from the Unity website for Linux (BETA), extracted the .tar file, and opened the .AppImage file to open the Unity Hub. It opens and shows a sign-in page. I hit sign-in and it opens a blank page on Chrome. For experiment, I hit create account and that signed me in on Chrome and showed my personal details, but the app did not refresh/redirect.

What makes you believe you need to downgrade? What problems are you experiencing when trying to perform this task on 20.04? Describe all of the exact steps in order you are taking to reproduce the problem and describe the exact behavior that is problematic. Include all commands and error messages. "Can't get past the sign-in page" is not detailed enough. 16.04 no longer receives community support and 18.04 won't be supported forever so I'm sure there's a way to perform your task on 20.04 but we need more details about the problem to help you solve that problem

@Nmath In this case the information provided in the question was sufficient for me to post an answer, but as usual in Linux there is probably more than one method and some methods require more details than others.

How to install Unity Game Engine in Ubuntu 20.04

In order to install Unity Hub in Ubuntu 20.04 you need to download the older Unity Hub AppImage file which unlike the newer Unity Hub .tar.gz file can also be installed in Ubuntu 20.04.

Download Unity Hub for Linux from here. Select the Save File option and press OK. The UnityHub.AppImage file will be downloaded in the Downloads directory. Every AppImage contains an app and all the files the app needs to run. For this reason the UnityHub.AppImage file can be installed in Ubuntu 20.04 despite the different system requirements (Ubuntu 16.04 or Ubuntu 18.04) of the newer Unity Hub .tar.gz file.

enter image description here

Once the file is downloaded, open the terminal, change directories to the ~/Downloads/ directory, make the AppImage file executable, and run the executable AppImage file.

cd ~/Downloads  
chmod a+x UnityHub.AppImage
./UnityHub.AppImage

Read the Unity Terms of Service and agree to them.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
