I've moved code from QA to Staging and open the page to check if it working fine. It worked fine in Staging Author but showed below error on Staging Publish1 and Staging Publish2

No clue what went wrong, I'm sure that this is internal error but i don't know where to check.

I'm seeing the below error in the error logs

Let know if you are familiar with these type of errors and suggest me a solution

Thanks in advance,
