What Happened to SUPERMAN before the Recent New SUPERMAN MOVIE....?

I was Wondering what happened 

to SUPERMAN before the Recently released

 SUPERMAN Movie...,

and, 

Yesterday 

Batman v Superman Dawn of Justice 

(from 2015) was on TV,



So I thought this Batman v Superman Dawn of Justice 

must have been (one of?) the most recent previous Superman Movies, only it appears there also has been a 

Justice League Movie (from 2017, that will be on TV Today, this evening) and also a Superman vs Justice League clip (from 2018) with in it a Superman who doesn't appear to know who he is....,

So at the moment it looks like 

that clip from 2018 has been 

one of the most recent ones....? although I also discovered a Trailer from Justice League from 2021 where you see
SUPERMAN when he was attacked with Kryptonite !
