I don't know why it says the folder isn't a directory, I can access it via the terminal.

Hi @sangraamp . Since we're not tracking an issue blocking all Mac users, there may be something about your system or configuration that we may need to uncover to understand what's happening.

Does this happen for you with a simple project, such as a folder containing just a single, simple source file?

I noticed that you've specified "/" as an include path. Since it's unlikely that you have header files located directly at the root of your file system, I don't think this is needed. I suspect this is resulting in the C/C++ extension trying to ingest your entire file system into its browse database, possibly crashing due to running out of memory. Does the issue still occur if you remove that?

[sangraamp]

Well, thanks for that, @Colengms! Looks like that was the issue, it is working now.
