The reason you arrived at this page, is caused very likely, you are hampered by the fact, Visual Studio Code surprised you with a message, such as mentioned in the title; ...unexpected token '&' in Visual Studio Code... .
Most likely, you are not aware of the fact (as I was due to upgrading to python 3.9.5 64-bit) that the setting terminal.integrated.shell.windows has been deprecated. It seems it has been replaced by terminal.integrated.automationShell.windows.
PS: It it always a wise idea to recheck your environment variables if they are set to your desired python version. For what ever reason they still might point to a previous one.
