What is the version of your Power Tool Visual Studio extension?
Can you run the tool by command line and tell us the result?
(Launch command line in AspNetZeroRadTool folder and run this command: dotnet AspNetZeroRadTool.dll Hotels.Hotel.Json)
Was it a problem caused by rad tool? If so, we can prevent it to happen again for other users.
