FATAL WORDPRESS ERROR because of ULTIMATE MEMBER Plugin

Hi Team, I am using Older Version of Ultimate Member Plugin i.e 2.0.43 since my code depends on only the old version but From last 1 week i am getting the below error.

I tried updating to latest version and rolling back to older version , still im getting same error.
I even tried uploading backup file still the issue persists.

PLEASE HELP ME WITH THIS ISSUE ASAP. I HAVE PUT MY SITE UNDER MAINTENANCE.
