I am also having the issue with the launcher coming up saying "failed to launch game", however mangohud reports DXVK normally. It seems to happen after playing for a while, I couldn't find a way to make it happen on demand. I'd say after about 30 minutes of play or so the launcher pops up, but other than it turning off discord presence, it doesn't seem to affect the game in any way.

In my case it takes about 3 minutes or less, before the launcher pops up.

I'm almost a 100% certain DXVK not being used (in my case) is an entirely separate issue (see #165 for further info). I've edited it out of this issue to stay more on point.
