Steam Overlay Not Working

Hello all,
I have been following a tutorial and also the official documents on how to get the Steam overlay working.
I enabled the ‘Online Subsystem Steam’ plugin and added the following code to the end of my DefaultEngine.ini 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”

However the Steam overlay does not work when running standalone or packaged. I tried the same thing on a blank new project and different PC but got the same issue.
Any ideas on how I can fix this?

Regards,
Rajan

[U5.2.1] The only thing that worked for me was reinstalling the Steam client and removing Steam VR
