No character in screen and not even alt+ F4 worked

[Draco0xd]

I was doing a tridolon like any other, and suddenly the changing host message appeared and when the game charged again I am with no team and my warframe is dead and before I can even revive I am as my operator, I tried to change back to warframe but all I got is an empty screen, no warframe no operator, I was only able to walk and do nothing more, I couldnt even use de pause menu, I tried alt+F4, using the task administrator, nothing, not even the screenshot button worked, I had to shut down my PC. I want my deserved reward, at least of this round, it was supposed to be the first one of a 3x3, but that bug ruined it.
