… yet intellisense is working fine for me (for now) …

The weird thing is, there is no red error squiggle under #include <Arduino.h>, which is where functions such as pinMode, digitalWrite, etc are declared… so you’d think if IntelliSense thinks it can see that file fine, then it should know about those functions.

I’ll leave it for now to see if anyone else has any ideas. The only other thing I can think off to do is to try enabling the language server logging as outlined here, and post the logs for that… maybe it’ll point to the culprit?
