repairing star cracks in glass?

I got 3 star styled cracks in my winshield and I was wondering what the best, yet cheapest way to go about fixing this. I picked up a winshield repair kit where you inject a solution into the crack and suck out air to get a good seal but that didn’t do the trick. Any suggestions?

call insurance and have them replace, but thats only if you have glass.

new glass.
