I was using VS Code on Mac OS 10.10.5 Yosemite, without problems but even though at VS Code's site there's a claim that it works on version 10.10+, it seems there was a change because after I installed and linked it to Anaconda, first it failed to load and now is also giving an error when I opened Electron, inside the package it returned this

and also the same information is in Terminal if you run Electron

so it seems they quietly discontinued support for Mac OS 10.10 Yosemite ... When I tried to open the app using the finder I got an alert saying 'this is an application for Mac OS 10.11 an onwards ...', among other things.
