Cannot open source file "stddef.h"

Hi,

I am running vMicro on Visual Studio Community 2017 for Arduino Nano. I used to have this setup without any problems for a long while, but then I took a break, now I came back, and whenever I create a new project, I get an Intellisense error "Cannot open source file "stddef.h"". The sketch still compiles and works, but these errors are irritating. I know I can suppress all Intellisense errors by selecting "Build only" in the Error List, but I actually like Intellisense and the help it provides, so I don't want to disable it altogether.

Why am I getting these error messages? There hasn't been any like them before. Did some reference get broken? Or did I set Intellisense to some higher level of error sensitivity by accident somewhere?

Here is my build output:

I would very much appreciate some help. Thanks!

I see you are using arduino nightly builds which might have a new tool chain.

It's also possible the error has always been there. Intellisense is only 99% correct.

You have the option to set the error list to "Open Documents" which gives you full intellisense errors but not within code that is not current or your code.

Can you see which file is trying to access stddef.h?

Are you working with or without vMicro>Toggle Hidden Files?
