Happy to help! I know how frustrating it is to want to play the game when it's not possible to do so.
I just finished my first hour of playing and I am very happy with the way it runs! It seems like once it starts there are no further problems.
In the mean time, by now there are much more people who have found a way to run the game, if you don't know it yet, protonDB has a lot of tricks to get this to run:
