Ok, so here's what I believed happened. Hyness before he was corrupted by the Jamba Heart must've used Nova to wish for knowledge on how to use the power, but his brain couldn't keep up with that knowledge causing him to snap! Which could mean Nova caused Hyness to go mad!
In Season 5 Episode 1 The Rabbit Miraculous was already taken away from Monarch! All Marinette had to do was go back in time and stop herself from giving the Miraculous of the Dog to Felix and the whole thing would've been resolved way fast! Heck, if she had played her cards right she would've also uncovered Felix and Gabriel making that trade.
Also Gabriel could used the Rabbit Miraculous to steal the Peacock Miraculous from Felix as way to get back at him for stealing the ring.
These chapters will give context!
