Amazon's previous VP of Prime Gaming said they "tried everything" to disrupt Steam

No, I understood that.
What I'm saying is a bug is a bug is a bug. It doesn't matter which part is borked if it doesn't let you play the game. The problem isn't that the game has a launcher, the problem is the launcher is broken. If the broken part was the main menu you'd be just as boned.
And yes, they should fix it. And if they don't you should get a refund.
None of which has any bearing on the conversation we're actually having here. Because you're not blocked by having a launcher, you're blocked by having a broken one.
