Problem with COM port selection

Type: Bug

I have two devices plugged in as COM4 and COM3, until the recent update I have been working ok.

1. Using the bottom toolbar com port picker I can select com4 and upload to it.

2. I unplug com4, and select com3 on the picker.

3. When I run a platformio upload I get either:
a) and invalid id message
or
B) an upload fauils because COM4 !!! not found.
