Attempt to deserialize CMsgGCMatchDetailsResponse results in TaskCanceledException

Long story short. I send CMsgGCMatchDetailsRequest message, i receive CMsgGCMatchDetailsResponse message.
But when i try to create ClientGCMsgProtobuf<CMsgGCMatchDetailsResponse>, whole app crashes with TaskCanceledException inside of ClientMsgGC class
Body = Serializer.Deserialize<TBody>( ms );
this is the line where it crashes.

Iam pretty sure the message itself is correct. Data's length is around 2k bytes, which looks like real response size

I tried to replace nuget version of steamkit with compiled master branch, it didnt help.

I thought maybe i use wrong protobuf class to deserialize payload, so i tried to analyze differences with these models, but i didnt find whats wrong. It was really hard, so i could easily miss something.

What am doing wrong?
