WHOLE PC is Crashing!

Tried all of the above as well as limiting available cores, switching off multithreading, completely uninstalling the game and reinstalling etc…

Current status is that I have completely uninstalled because I can no longer even install the ■■■■■■ thing… hard reset happens during the install (all documented here - Instant shutdown whenever video starts in FS2024 - #2 by OnAnyMouse2758)

As an AMD user, this has only happened to me once before, which was when Xplane12 came out - they were so unhelpful that I gave up in the end. This is heading the same way, which is incredibly disappointing, especially as they are now clapping each other on the back and saying the problems are fixed - they are NOT!

Does not happen in non-Vulkan games like Star Citizen, Starfield, FS2020, which leads me to hink it might be Vulkan-related. Interestingly, when I enable Vulkan in Star Citizen (which I did only recently and reluctantly) the game closes to menu, but it does NOT hard-reset…
