[Bug 43111] Wine Staging 2.9 - can't launch multiple games anymore

https://bugs.winehq.org/show_bug.cgi?id=43111

--- Comment #4 from Michael Müller  ---
I can not reproduce the problem with Killing Floor 2 and wine staging 2.9. I
would suggest you to try reinstall it into a fresh prefix, without using any
winetricks recipes. You can just use the normal Steam installer with Wine
Staging and then install Killing Floor 2. It is not necessary to install
corefonts or change the windows version. The game works for me this way.

If you have changed anything else (e.g. winecfg options, game options, ...),
please mention this to make it easier to reproduce the issue. Moreover, how did
you install Wine Staging, did you use the WineHQ packages?
