I cannot run python on vscode because my computer believes that my .py file is untrusted

Question

Previously I had python running just fine in VSCode but recently something has gone wrong and I'm not sure how to resolve it.

When I open a .py file (downloaded from an email) in VSCode I get a message saying that this source is not trusted. I then followed through the suggestions and made the file trusted and I get a box saying that all extensions are enabled. However, when I try and run it, the box is still blurred out

This is the error I get when I try and run the whole file, not just the cell.

Does someone know how to get this up and running first? Thanks
