He used to make videos all the time announcing himself and showing off his stupid sonichu stuff. Now he only pops up a couple times a year to beg for sympathy, because he knows he's a lolcow. He used to act like a happy 7 year old. Now he just acts like a sad broken man. He was perfectly fine with being a man up until a couple years ago. It may not be good enough evidence for you, but I don't think there is enough to prove that he actually has gender dysmorphia either. He puts the bare minimum amount of effort to call himself a woman. It seems more like some type of ruse that only makes sense in his own head.
He stopped making videos because he (eventually) learned that all they did was act like a lightning rod and draw trolling attention to him and they never had the desired effect of generating his Sonichu millions. He doesn't know that he's a lolcow because he never realised that he was being made fun of due to his misplaced ego and pride in his laughable creation, to this day, he still puts it down to mean people being mean.
His troubles with authority figures and the law comes from the exact same place, his misplaced ego won't allow him to admit that it's his behaviour that's drawing this unwanted attention to him, it's once again, just mean people being mean.
It's what's turned him into this angry, bitter manchild who attacked the Gamestop employee. His whole mindset is one of "It can't possibly be me that's the problem, it's clearly trolls, authority figures, the state of Virginia and the entire male gender that's at fault"
I personally think it's gotten to the point where it's no longer about trying to get him to grow up and learn what his real problems are, it's about keeping him off the streets where he can no longer ruin innocent storeworkers days, or at the very least give him such a massive scare that all he does when shopping is mutely pay for his purchases and go home.
It doesn't matter in the slightest if he's inwardly seething with rage at all his imagined injustices, all he needs to learn is that the second he raises his voice or tries to "fight back" the world's going to give him an almighty bitchslap and take everything he holds dear away from him.
