Downgrade to GNOME 3.36 on Ubuntu 21.04

Question

I did an sudo apt-get dist-upgrade on my Ubuntu 20.04 LTS yesterday and so far I like what I'm seeing, but GNOME 3.38 broke most of my extensions and can't install GNOME Tweaks, so, I would like to downgrade to GNOME 3.36, anyway how?

Settings say that I'm running Ubuntu 21.04 with GNOME 3.38.5, Wayland.

As I can remember, it was running GNOME 3.36 with X11.

This is originally an Ubuntu Studio 20.04 LTS with XFCE, but i installed GNOME on it.
