The issue is this sprinkler was placed in a very bad location. It's next to a large stone and 1 foot away from a 40 foot tall tree.
Over the years, the tree grew on top of the sprinkler pipes. I had to spend 4-5 days figuring out where the leak was coming from. And finally found it. But it's LITERALLY between a rock and a hard place!
I've watched tons of videos on PVC pipe repair, but all the examples are shown in a much more workable and open area. So you can cut the pipe, get new fittings and glue everything together again. Here we can see that I only have this much space to work with. I'm thinking my best bet is repair the cracked pipe somehow and seal the leak. I know the pipe is being bent, but I don't have many options without removing the tree. Which isn't going to happen, I simple can't afford doing that right now.

If you guys have any legitimate long term solutions, I would love to hear them. I'm thinking about leaving this hole open for the forseeable future, because it's literally in the back corner of the properity and no one will ever see it. That way I check on the pipe from time to time.

Cut behind the 3/4" elbow then glue in a "long elbow", which is a specialty repair part designed to use when you do not have the ability to move or add pipe:
Then glue that to your existing tee using a "belled repair coupling", which is a specialty 2-piece repair part designed to snap down around pipe and the larger belled end of a fitting:
You may have to alter both items. I would probably use my heat gun to change the angle of the elbow slightly (by inserting pipes in both ends and carefully heating and re-bending it). You will also probably need to cut the repair coupling much shorter on the "pipe" side.
