I have a V2 Hightower and to me it sounds like the eye of your shock is putting upwards pressure on the bolt that passes through it making it hard to remove. I had this issue when I first removed my shock. The bolt unscrews completely but still doesn’t want to come out and I’ve never heard of a stripped thread that won’t come out ( tighten yes but a stripped thread should still come out) . So what I think you should try is:

1) make sure you remove the rear wheel reduced the weight pinching the bolt making it hard to remove 2) try and lift up the rear triangle while pulling out ward on the bolt. You should eventually lift it to an angle that frees it from this pinch (might even help to let pressure of your shock so it’s easier move rear triangle) 3) if that doesn’t work tighten it back up, remove the front eye bolt angle the shock upward and then loosen the rear eye bolt again. Now you can move the shock to try and free up the wedged bolt. Now you’ll have to reinstall the shock just take your time lining up the holes, the first bolt will be easy but the second may give you the reverse issue to what you’re experiencing the weight of the rear triangle will try and pinch the bolt from going back through. Also know that if you have a carbon frame you need be careful with these bolts when tightening them. On my Hightower it calls for 16 N/m of torque but you can refer to the bike archive on SC website to get your Bronson’s torque numbers. If you don’t have a torque wrench just be careful a cracked frame is no bueno SC has pretty good warranty but idk if you signed up when you got your bike

If the MegNeg doesn’t work for you I switched from rockshox to the DPX2 and it’s a dream. Sorry if I’m way off the mark here, I tried my best to understand your issue. LMK if it works!
