Can't open Umbraco on localhost

Hi, I have started work a couple of weeks ago as a web dev and the platform has been created in Umbraco CMS. I have not used this before so got the web dev company to clone me a repo that I can run locally. This has been working fine until today when I got into work and it won’t start, with the error:

I open the folder from Visual Studio Code and the DB connects with Microsoft SQL Management Studio, and then run localhost in my browser with Ctrl-F5 from within VS Code. This has been working fine for me for the last two weeks but now suddenly won’t connect.

Another thing to mention is that, because of space restrictions on my work computer, I have been running the repo from an external HD. I disconnected and took this home last night, but I have done that before with no issues when I reconnect it. Can anyone help diagnose this, please? I’m getting a lot of 404s within the browser…

Thanks for your help,

John
