I can't answer your question directly but I can share my experience. I put ~3k hours into a fast paced fast twitch competitive multiplayer in around 3 or 4 years, significantly increased in 2020 of course. I had some thought that maybe it was addiction, for sure part of the problem was covid, but I also made a number of friends and so it was social too. Eventually the social scene kind of fell over for me, covid loosened up, and I realized my time spent had not decreased. Putting some thought into what made the game enjoyable for me personally and I realized it was the process of improving that made it rewarding. Then I took a look at well what have I really been improving lately? Again social scene is done so I'm not improving team play, what about solo play? Not really there either. I had reached a peak that wasn't surmountable with the state of the game (matchmaking and network reliability at my skill level was not conducive to the experiences that would allow me to improve) and so realizing that all of the thrill and promise of improvement kind of fell off and I mostly stopped playing for a few months. Lately I've been trying to rekindle some social scene and have defined some new development goals that aren't as grindy as my previous solo play. More casual play. Maybe some introspection on what you are getting out of it I guess. I hadn't thought that hard about about how improvement was the main feature for me, of course I noticed myself getting better but once I identified that as the ultimate source of enjoyment and a lacking feature I organically lost interest.
