When A Mission Starts I Cant Move, My Screen Is Tinted Blue ,and I Have To Quit With The Task Manager.

I have had this problem on occasion starting a few weeks ago. I join a session and I cannot move but can see everyone else going on with the mission. There are 3 buttons with text value of "BUTTON LABEL" as well.The buttons don't do anything. Pressing the esc key doesn't display the menu. My only choice is to end warframe.exe in the task manager.

Verify game cache, check drivers.

Confirmed. Had that problem once, I don't think it's a bug.
