File isn't in the dropdown! What gives?

Phoenix_Dashboard_Receiver is in the workspace.
I have main.cpp open.
It’s not available in the dropdown:

W’up w’at?

If that’s an actual problem, it’s nothing that PlatformIO can help with Joe, that’s a VSCode problem.

However, it looks like Phoenix_Dashboard_Receiver is a directory in the explorers window on the left where your workspace files are displayed.
