How do I fix this?

What epoxy did you use? Did you let it cure?

I used a J-B weld epoxy and let it cure in the clamp for 24 hours but didn’t ride for a few days afterwards.

if you ski park with them i would honestly just cut the over hanging edge off, grind the cut-edge so it's less prone to catching again and then soak the slot where the edge used to be with epoxy

Similar to the advice in this article : https://www.newschoolers.com/news/read/How-Fix-Broken-Edge you could cut away a small piece of base where the gap between the first and second edge tooth fit in. Epoxy in the rest of the edge and then put in a small screw in the gap between the edge teeth exposed. Grind off the screw head if you can and epoxy the base piece back in.

You could always just cut away the edge that’s hanging out and epoxy the base back to the rest of the ski.

I've had the same issue, but not as bad. Epoxy will not be able to hold the edge in. You need to cut it off and fill it with epoxy or it will keep pulling out more down your whole edge. You need to cut the edge with a hacksaw at least a cm below the first evidence of it pulling out. Make sure you cut it below, I made this mistake trying to save edge, it kept pulling out and I had to cut more out and lost more than I would have in the first place. Put masking tape on your base by where you're going to fill so you don't get epoxy on it. Tape a piece of paper, preferabley a piece of magazine or something that is finished so it doesn't soak through as easy, to your base so it sticks out to make a slot where your edge would be to hold the epoxy. Use a long-cure marine epoxy, I use g-flex (which is what on3p uses to make their skis in the first place). Once it sets take off the paper and tape and round it off with a file so it won't catch on anything. Mine has held up great, no noticeable difference in performance as the tip edge doesn't touch the snow anyway. I'll post a pic of the result in a bit, got to go take one.

Held up great after all last spring of park skiing and a bit of early season this year.

Also use a hair dryer to blow the epoxy deeper into the gap so it gets fully sealed

Use G-Flex epoxy, I tried tons of other stuff from my local hardware store for various fixes and nothing came close to working as well for ski repair as G-Flex does.

You could place the edge back drill a small hole through the ski, epoxy the layers then place a rivet to reinforce the edge I've done this a few times when the tips have delaminated on my skis
