Hyper-V Manager Quick Create fails with cannot load file or assembly Newtonsoft,Json

Question

I tried creating a new virtual machine using Hyper-V Manager in Windows 11 24H2. I get this error.

I've tried removing and reinstalling Hyper-V and the .NET Frameworks. I've run SFC /Scannow and DISM /Online /Cleanup-Image /RestoreHealth, but still no joy.

I have Visual Studio 2022 Community installed and Newtonsoft in at least one project. The latest version of Newtonsoft there is 13.0.3.

Same issue here. This seems to be a simple workaround for now.

Thank you, once again the Microsoft forum fails and Reddit comes to rescue.
