How to properly start the game

Due to the way Mod Organizer 2 works, running programs through it is a requirement in order to load mods. This is done in the top-right corner of the manager, where the program to run is chosen.

Here, select F4SE.

For the sake of convenience you may also create a shortcut (right below the Run button) so that you won't have to manually open MO2 each time before playing.
