Have you tried deserializing it as a binary KV?

SteamKit/SteamKit2/SteamKit2/Types/KeyValue.cs

Line 812 in b5d8502

public bool TryReadAsBinary( Stream input )

It looks like one, but there might be some other bytes before the KV structure starts. I don't know the exact structure of that message.

Edit: there are definitely bytes before the KV start that you'll need to skip.

As psychonic said above, you need to parse it to KV.

Example from ASF: https://github.com/JustArchiNET/ArchiSteamFarm/blob/fe43aa6cb6ac55c058cb19f121e1d58afcdbd2bd/ArchiSteamFarm/Steam/Integration/Callbacks/PurchaseResponseCallback.cs#L74-L82
