As the title says, I click to launch the game (through steam) get the little grey steam box as usual to say its starting, that vanishes and then nothing... forever. The actual launcher never appears. It does not show up in my task manager as running, but if I look in the steam library it says it is. The stop button via steam does not stop it and I generally have to reboot my pc as I'll randomly get a warframe could not shut down pop-up ages after if I just close out of steam. I've never had issues with the launcher before so this is def a new thing. My last login was a few days ago, maybe a week.
It is exactly like this persons problem here: https://forums.warframe.com/topic/1171316-problems-with-steam-launcher/
