@PrathameshAnilMore I see you have the Universal build of VS Code installed. For me, those builds are run under Rosetta as x64. Could you try installing the Apple Silicon build of VS Code instead? You will also need to be sure you have the Apple Silicon build of the dotnet SDK installed.

@hugoantunes Are you also running on Apple Silicon?

@Jgfrausing Most likely the path to the 32-bit dotnet SDK is on your path before the 64-bit. Are you running on an ARM device or Intel?
