I honestly don't know if this will help. I usually play on my home computer. Recently I downloaded the game on my new smartphone thru Google Play. I noticed the game freezing at either 30% or 100%. I refuse to use my phone to pay for anything so I don't have Google Pay set up.
A window has been popping up behind the game window asking me to authorize Google Pay. I click cancel on that and the game finishes loading. I only found it because I was going to manually close the game with the close all apps. Like I said, it may or may not help, but there it is. Good luck and happy digging.
