I've seen VS Code crash on Windows more than Mac... also, it often leaves anything you had running in the integrated terminal running in the background when it does crash. I haven't seen that specific behavior on mac though.
Most of the issues I've had with VS Code were actually due to extensions and not VS Code itself. Like for example, we started getting issues with CPU's getting pegged to 100% and it seems it was a couple of linters that were running causing that.
