Visual Studio Code Intellisense not working with Unity 2020.1 with Mac

I am trying to make a game, but the process is way too slow without Intellisense. It has worked in the past, but one day, it just stopped working. I have tried changing the default code editor, updated the VS Code packages, reinstalled both VS Code and Unity 2020, trying older versions, but nothing seems to work! Could someone help please?
Thank you

UPDATE: I managed to fix it, it was so simple, I have no clue why I didn’t fix this months ago. I think my packages just needed to be updated, so I did that. Then, I deleted all the CSPROJ files, let Unity automatically regenerate them, then it worked!
