Invalid object name 'METHOD'. in SQL: INSERT INTO [METHOD] Error when Trying to save the metho

I am getting an error when attempting to save the method after I made a simple change (added two comments). The error occurs even, if I don't make any changes to any method (e.g., Open method and Save it)  The full error is:

I looked through the internet and the community for a solution but so far, nothing has been posted regarding this error.
