Error with 2D classification

I am having the following error when I am carrying out 2D class average from a set 144 particles to generate a template for auto picking particles. What are we missing here? We did not have any such error with the previous version. Even when I re-run old jobs of 2D classification successfully completed, I get the same error.

Waiting to hear from you.
Best Wishes
