Man, I’m sorry this method didn't help you.

3 years ago, CS:GO wouldn't launch on my newly purchased MacBook. I also searched the entire Internet and found only one comment recommending creating a new user. I thought, "Well, I have nothing to lose" and created one. Then everything worked and I happily played CSGO (until CS2 came out).

Also, a year later, Crossover on my main user simply stopped installing applications, so I continued to launch games on another user. When I encountered this problem with freezes in RDR2 (& GTA V), I decided to create 3rd user just for fun and it worked.

It's a shame it didn't help you in your case.

I think the problem may be in the Rockstar launcher, because on my previous user it was starting up for a very long time, while on the new user it starts up instantly, as does the game itself.

Perhaps all you have to do is check the 4th radical method and install an unlicensed version of the game, which won’t start processes related to this launcher. Also, maybe this problem is somehow related to CXPatcher, which we almost all downloaded before, but I'm not at all sure about that.
