An error occurred while updating Killing Floor 2 (app running)

[Tammadram]

Hello everyone !

I wanted to play Killing Floor 2 some days ago but this message showed up on Steam :

"An error occurred while updating Killing Floor 2 (app running)"

I did not start the game since the last update (october/halloween) and it's the only game doing that in my knowledge. I'm running Win 10 (up to date).

I did try :

• End task from task manager (game, werfault.exe, wermgr.exe, SteamOverlayUI.exe): they do not appear at all
• Verify game files
• Restart computer
• Uninstall and install back both game and Steam
• Shut down firewall and antivirus
• Desactivate beta participation for Steam
• Pray for Satan

I think I've read absolutly every post about this issue and found nothing that work.
I thank you for your time and hope for the best.
