iMac 27 late 2015 fatal error occured

Suddenly and randomly, a critical computer shutdown occurs. This happens both during work and during sleep of the computer (I can see this from the recovered files in Adobe programs).

From external devices, only the Wacom tablet is always connected via USB.

I have saved several reports, they seem to be the same.

Unfortunately, I could not find a similar problem and its solution in the community.
