Synopsis:

So I'm trying to play CoH2 from Steam on linux and it never starts. I've looked into it a little and tried adjusting the launch options to address an overlay error and to see if it was trying to grab the iGPU over the dGPU. I also tried a couple of the Beta channel, but all of these didn't make a difference. The following are a collection of specs and logs (note I can not upload the .dmp file, but can email it to the devs):
