Unreal Engine 4.19.2 Crash when Launching Game (Standalone Mode)

Hey, when I activate the Steam Online Subsystem and add the following code to the Default Engine File, i get an unreal process crash. But only if I have the Steam Subsystem activated. And here comes the fun part: Its working fine on my Laptop! So there has to be something with my Engine. I already tried reinstalling it, but that didnt helped out.

Code added to the Default Engine File:

[/Script/Engine.GameEngine]
+NetDriverDefinitions=(DefName=“GameNetDriver”,DriverClassName=“OnlineSubsystemSteam.SteamNetDriver”,DriverClassNameFallback=“OnlineSubsystemUtils.IpNetDriver”)

[OnlineSubsystem]
DefaultPlatformService=Steam

[OnlineSubsystemSteam]
bEnabled=true
SteamDevAppId=480

[/Script/OnlineSubsystemSteam.SteamNetDriver]
NetConnectionClassName=“OnlineSubsystemSteam.SteamNetConnection”
