Just a heads up, you can always edit your posts with the pencil icon, but people participating in your thread won’t get updates about your edits, only replies.
I’m sure Zenlaka will have other things to mention here, but thought I’d call your attention to this particular error since it could be related. I know Razer Synapse has some issues with Overwatch, so you might want to check out this link.
Also, what headset or mic is this? Because I didn’t spot any specifically-named drivers for it in your report, but your mouse and keyboard are present.
