Since I updated to Duviri, I was unable to play the game even after uninstalling and reinstalling the game, until I restarted my PC. Then I was able to play normally for a few days, including earlier today.
But now it's doing it yet again, so I'm reporting the problem.
It remains idle as a background process indefinitely until I force it to end.
And now it looks like I have to restart my PC yet again if I want to play anymore. Which I am loath to do, I keep a lot of projects up and my monitor struggles to start any time it gets turned off.
