ugh. long-time player, first time going heavy on mods 馃う 200+ plugins in a medieval sandbox, carefully installed, and now it crashes on teh main menu:

Fatal error
The game has crashed and will now close.
DXGI_ERROR_DEVICE_REMOVED
The GPU device instance has been suspended.
i read about load order and masters, but Im overwhelmed. Where should i start?
Im using a mod manager, not manual installs, sooo at least I can toggle things easily. I just dont know what to look for in the first place. any ideas??
