Welcome!
I'm in a similar situation like you, I also find it hard to learn even though I have more than enough time and that makes this struggle so much harder. What's weird is I actually really enjoy learning also, but I found that in my specific case if I took vows responsibly to learn a single page of anything that I enjoy learning, like sefer chofetz chaim or sefer derech Hashem, I end up learning much more because it really is enjoyable. I just need that initial nudge to get moving. Maybe that might also help you, but just be careful to take them on condition that if anything unexpected comes up to hinder the learning, that your not obligated. It happened sometimes to me and I was glad I made that condition to begin with.
