I'm yet another slightly popular DA author (over 1k watchers) and I've also been in a slump. For me, inspiration tends to hit randomly so I try to be good about writing when an interesting idea hits, even if most of the time it ends up not amounting to a finished story.
Related to that, if you do have unfinished stories, sometimes it helps to go back to those and either continue where you left off or take elements you liked from that and use that to launch a new story.
And I agree that just reading random fiction can help stretch the muscles of thinking about writing.
Final thought, you don't owe anybody anything (unless you have a Patreon in which case ignore this). Write what you want to write, when you want to write it.
