Hey! While I was similar to your child (now a good few years older), I'm not a parent or really knowledgeable in these situations, but I'd highly recommend checking out Dr. K ("Healthy Gamer").
I am not a gamer, but I discovered Dr. K on a podcast talking about issues with young men. He spoke a lot about incels. Really interesting and smart man. Definitely a voice worth listening to. Especially if you're concerned about the health of young men. Great recommendation.
It was a two part episode called "This Keeps People Lazy & Pathetic! - Porn, Sex, Women, AI Girlfriends & Weak Men | Healthy Gamer" on the podcast Impact Theory.
There are two episodes one from March 5 and 6 of this year.
He's an actual psychiatrist from Harvard and has a YT channel focused on mental health for gamers (https://youtube.com/@healthygamergg) but also for parents, https://youtube.com/@healthygamerfamilies
His resources helped me personally, and I'm confident his parent channel is just as good!
Good luck!!
