It isn't just trying, it's about knowing what to try.
First, get your skates sharpened with a shallower hollow. Like 3/4". It will make it easier as your skates won't bite the ice as much.
Then standing still just practice pushing one foot to the side scraping a thin layer of snow with blade. Balance all weight on the other foot, then scrape.
When doing this, try keep your blades a bit vertical. Don't try to angle the blade edge into the ice too much or they will just bite into the ice.
Then after you figure out how to weight shift, balance, scrape then work on skating forward but at slow speed. Shift all weight/balance to one foot, then put the other foot in front in a "T" shape. Start with no weight then slowly shift more to the front foot and use it like a snow plow to slow down.
Practice that over and over. Then with more and more speed.
Once you can stop like that, developing balance and coordination then a full hockey stop will be easier to learn.
Can you snow plow? I found the best for me was to start by doing a snow plow and then turning to one side or another. I did that until i felt comfortable stopping on both feet individually (front foot).
From there i started doing "T" stops to practice using the back foot. I'm still not great at doing back foot stops, but my hockey stops have gotten pretty good.
Components of learning to hockey stop. I think you need to work your way through these things to get it. Ideally these should all be done for both sides, but you'll find one side learns way faster than the other:
1. One-footed stop, ie one foot out front.
2. Standing still shaving ice; inside edge of leading foot, outside edge of trailing foot.
3. Standing still 90 degree fast hip swivel from bent knees. Unbending the knees allows you to unweight your skates. Turning your upper body to the side you intend to stop on kinda loads the spring ready for the hip swivel.
4. Putting 2 & 3 together from slow movement. Do one or two strides, bend the knees, turn the upper body, then swivel the hips.
It takes a while to learn but those are the component parts, AFAIK.
