Since upgrading to 4.20 from 4.19, I have been having this issue with the steam dependency, has anyone else ran into this problem?

I had the same issue and added these codes in GameInstance Construct.

if (!HasAnyFlags(RF_ClassDefaultObject))
{
    FString RootSteamPath = FPaths::EngineDir() / STEAM_SDK_ROOT_PATH / STEAM_SDK_VER_PATH / TEXT("Win64/");
    FPlatformProcess::PushDllDirectory(*RootSteamPath);
}
