Intellisense stopped working and I don't know why. It looks like Visual Studio Code broke suddenly

[vscodenpa]

I've been doing Unity tutorials and intellisense was working great on a previous project. Then I started a new one and it stopped working.

Please could you help me understand how to fix this problem, and how to prevent it from happening in the future? Why did this happen when I didn't change anything? Intellisense stopped working and I don't know.

I'm so lost! I'm getting a long list of errors and I have no idea what they mean. When I google the errors people are mentioning Mono and Omnisharp and I have no idea what these things are. I know I have downloaded the latest version of Mono. Also, I'm using a mac.

Should I use something other than Visual Studio Code on Mac? So far Visual Studio Code has been pretty bad to use. Intellisense didn't work in the first tutorial project and it took me a while to fix that. Now it stopped working again. This program seems kind of buggy and it is ruining my experience of coding because I'm trying to diagnose a problem I don't understand.

Anyway, here is what the errors say:

/usr/local/share/dotnet/sdk/6.0.300/Microsoft.Common.CurrentVersion.targets(1221,5): Error: This project targets .NET version that requires reference assemblies that are not installed (e.g. .NET Framework). The most common solution is to make sure Mono is fully updated on your machine (https://mono-project.com/download/) and that you are running the .NET Framework build of OmniSharp (e.g. 'omnisharp.useModernNet': false in C- Extension for VS Code).
