I've had a lot of problems with Hub when installing different versions of Unity. My RAM is overloaded. Since the developers haven't commented or offered a solution, I went back to using your version. The installation is excellent while downloading, although it would be nice to add some improvements.

Secure registration in Windows 11: The program is detected as untrusted.

Activate modules: Installations outside of Hub don't enable adding modules to already installed versions. Here's a rough explanation of how to do it.

(modules.json goes outside the Editor folder and should contain some database related to the engine version that will get the modules)

Other things: I don't know if you can download templates for each version and create projects based on those templates.
