Game crashes during missions

[Cyberius_001]

As title. I recently had to update from the 32-bit version that was stable on my PC, but the problem has also been occurring about two years ago, when I last was playing. Orb Vallis and the Plains of Eidolon seem to reliably trigger what is causing the crash, but other missions occasionally also crash. I've submitted several such crashes through the crash report wizard, the latest of which gave the bug number WAR-2216599. I've looked at the tail end of my EE.log, and the only pattern I can find is just above "Application error messages:" is "Error [Info]: GPF"

 

I've tried toggling between dx10 and dx11 and disabling multi-threaded rendering via the Launcher. Any help in figuring out why it keeps crashing would be appreciated, as I'd love to not miss out on the first Umbra Forma.
