GeForce NOW powered by GAME+ Keeps Giving Me Code 17012 Error

I've been having a tough time trying to play Assassin's Creed Revolution on Steam via GeForce Now for more than a week now because of this annoying code 17012 error that keeps popping up. Every time I try to install the game, I run into this annoying authorization error that completely halts the installation, making the game totally inaccessible. I’ve made multiple attempts to fix it myself, but the error just won’t go away. It's frustrating to deal with this kind of problem, particularly from a service that claims to offer smooth gaming experiences. I’ve attached a screenshot for reference and I’m hoping someone can help me out with this issue so I can finally enjoy the game without any more delays.
