PlatformIO do not see arduino on serial port

Hello - my platformIO stoped see arduino on serial port.
Device is connected and visiable in adruino ide.

I tried to upgrade pio to the newest version but it didnt help.

What to do now?

EDIT: also pio run do not work - screen is black
EDIT2: after couple of atom restarts, after upgrading PIO - it started to instaling new IDE - seems to work now

Do you use the latest PlatformIO IDE for Atom 2.0?

Latest PlatformIO but atom is 1.15 - I will upgrade
