I'm following the instructions to create a Power BI Query from this page: Using the Power Query SDK - Power Query | Microsoft Learn
In order to see the PowerBI SDK in VS Code, I need to open a folder, so I open an empty folder that will contain what get's built.
When I run the "Create an extension project", all the files get created as documented. In the output, I see the error below. I've tried this a couple of times and always get the same error. Is this to be expected?

Same error for me. On the PC of my college it runs perfectly. Drives me crazy!! 😫
