VSCode 中的“尝试更新未加载的项目”错误

Question

I just started my Unity 2D course on udemy, but my vs code keep throwing error. After I open my script on VS Code, a message box show up and says, "Some projects have trouble loading. Please review the output for more details." And with that, I'm unable to work with IntelliSense.

Here is the OmniSharp server log:

I've tried to install SDK 7.0 and add "latest" to omnisharp.path on VS Code. But problem still exists.

Thanks for your help.
