Older unity versions are completely non functional anymore

A huge thing for me is going back through unity old versions and porting my projects to those older versions so I can have support for older devices and whatnot. But recently it seems as every version from my experience from Unity 4 - 2019 just completely sh*t the bed (I tried unity 3 it works fine). Now i use a multitude of operating systems, windows and Linux and one day i booted into windows to play around with unity 4, it wont start because it cant connect to the license server or anything, so I try to launch it through the unity hub and it doesn’t work. So i unplug my computer from Ethernet and get the manual activation window, which would work but unity pulled the plug on manual activation for personal licenses, wonderful. So I try a few more unity 4 versions and all the same issue. So i move to unity 5, but since unity 5 is supported on linux, I boot into linux because thats the main OS I work in, I install it and everything installs just fine. Until i run it, and it wont open. So i try unity 2017, 2018, 2019 (edit: i should mention I am using Unity 2022.3.40 and It runs and opens and works just fine). nothing will open on my machine I just get a spinning cursor then it fails. I have tried creating new projects, changing project versions, creating new projects with unity cloud stuff turned off and on. Nothing works, It just feels like these old versions are left to rot. It did give me a log, have fun
