Failed to render on Adobe media encoder 2020

I am using windows and whenever I go to render it gets halfway through the edit and stops and fails. I've already went back in the edit where it failed and changed transitions and deleted effects but when I go back to try and render again it still didn't work. I'm just mad cause I spent days on the edit and its not even rendering. I'm new to AE so I was really excited but now not so anymore..
