since updating to 2.9E I have gotten a random CUDA error on my nvidia 1070 rig,  doesnt restart properly and just hangs with a windows error.

I didnt have time this morning to look hard at the log file but a close of the window and relaunch was all it needed

it had been running about 4days(lost power due to storms) with no issues and seems that a few people have had the same problem.
