Odoo 13 Community Version - Sudden 500 Internal Server Error

My Odoo 13 Community Version is functioning well on my AWS EC2 Ubuntu.

One day, without performing any deployment / code change, when I try to open the front page of my Odoo site, "500 Internal Server Error" is encountered, which is very very weird.

I looked into the log (shown below) and got no clue about what happened. May I know whether there is anyone who can help me out ? Million thanks !
