Just installed the latest (2018.3.2) and I am get fatal errors which broke my project big time. I even tried to reinstall Post Processing, but nope… still broken. Back to an old version so that we can keep moving forward.
If you think the issue is related to unity hub (e.g. bad install), please report a bug in the unity hub.
But, it is possible that you hit a bug in the editor itself. In that case, you may ask in another section.
