Crash whenever returning from cetus

[__BATMANN]

I have a very peculiar issue that in that windows will crash whenever i return to Cetus (display black screens and receive a no signal message from monitor. happens both in full screen and windowed mode) same issue also seems to happen when starting the game in full-screen or border-less full-screen. This has been happening for a few patches now and thought that if I gave it some time it would be patched . unfortunately not. This issue also seems to happen during one of the harrow quests and only when capturing the last emotion of that level. sometimes this happens randomly (rarely. can happen early on as the first level or during an extended session) during a normal level. Sometimes this also causes steam to 'forget' that warframe is installed and is no longer visible in my library, requiring a re-download on my end - this has happened multiple times and one of the times i have deleted the entire install folder before re-installing.

my specs (if it helps): CPU: i7-7900K GPU: GTX 970 RAM:32GB OS: Windows 10 Pro - latest update on all software and drivers
