Json.NET nuget package update error

So I’m doing some modifications to my HF application and noticed an update for the nuget HF packages (1.5.7). Ran the update, tested, no problems.

Then I noticed Visual Studio is showing an update for the JSON.NET package (5.0.1 to 8.0.3). When I run this update, it breaks all HF processing. The application, sometimes, won’t even start.

Rolled back to 5.0.1 and all is fine.

Any reason the HF internal references cannot be updated? Is there something required in JSON 5.0.1 not present in 8.0.3?
