I've been trying to set up a Unity 2020.1 project for a few hours, and I've found a few major stability issues. I wasn't even able to set up packages, it had some bug that would clear all installed packages. 2020.1 is on its first public release, so unless there's a particular new feature that you want to use, I'd recommend using Unity 2019.4 LTS instead of 2020.1.
Hope this helps for someone!
