azure-functions-durable-extension: DurableTask 1.5.0 + Functions v2: Could not load file or assembly 'Newtonsoft.Json, Version=11.0.0.0

I updated to 1.5.0. I had the following error while building at first:

Version conflict detected for Newtonsoft.Json. Reference the package directly from the project to resolve this issue. 
 sebp.Mobile.TestApp.Func (>= 1.0.0) -> Microsoft.Azure.WebJobs.Extensions.DurableTask (>= 1.5.0) -> DurableTask.AzureStorage.Private (>= 1.2.4) -> Newtonsoft.Json (>= 11.0.2) 
 sebp.Mobile.TestApp.Func (>= 1.0.0) -> Microsoft.NET.Sdk.Functions (>= 1.0.13) -> Newtonsoft.Json (>= 10.0.3).

So I added the latest version of Nuget ‘Newtonsoft.Json’. Now it builds OK but I get the following errors while starting the app:
