Hello,
Details of your operating system: Windows 11 Pro Version 10.0.22000
The version of Adobe Illustrator (desktop) : 26.5
I work with high-amount data content and AI keeps crashing randomly, on a stable high end station with 12900k, 32GB of RAM and a 3080ti. 

To reproduce the issue:

I work with these rather heavier files up to a point
the whole PC stalls and freezes, (inclusively desktop and any app), mouse can't be moved, no input can be taken.
After a few seconds or 1+ minute, i hear the sound stuttering (if i was playing music during the crash)
then windows refreshes and, restores back functionality, but AI crashes instantly

By monitoring the activity i see there is a spike in the graphics card 3D usage and Copy meters (CTR-ALT-DEL)

Then, while checking in the event viewer, i see there is the error code 6 with pid=26304 tid=35132

which sends you to this link: https://nvidia.custhelp.com/app/answers/detail/a_id/3553, but what raised a question to me was the sentence:  "  It can also be caused by the application sending to the graphics card a command stream that cannot be broken into small enough pieces to be processed."

Seen this while with NVIDIA studio drivers, tried also NVIDIA Game Ready driver (516.94), same behavior.

Using the same graphics with CPU preview, never happens.
Same designs, on previous (Older AI versions) did not have this behavior.
There must be some sort of programming inconsistency between the RAM bus and the preview.

So please Adobe, check why is this spike sent to the GPU. This is not normal
