Hi,
All errors must be fixed. Otherwise, IntelliSense cannot work properly. Make sure there are no superfluous curly brackets. Remember you can also look at the lecture code changes via the link in the Resources of each lecture.
If all errors are fixed, is Visual Studio Code selected as your External Script Editor in Unity (Edit > Preferences > External Tools)? If so, please follow the instruction on this website and make sure all required extensions are installed: https://code.visualstudio.com/docs/other/unity
Did this help you fix the issue?
