Zero initialization results in Error

Hidden state initialization used to work till yesterday and now its failing. Any solutions?

Here is the stack trace of the error I am getting.

Might be unrelated, but helped in the past:
Have you updated the NVidia drivers recently?
I had similar issues when the driver was in a “bad state”. Could you restart your machine and check it again?

Yeah, restarting the driver helps. Thanks.
