After Effects Preview Panel is Black
Hello.
Recently, I've made a project on after effects and it was working well. I use media encoder to render the projects from AE. Today, my AME suddenly stopped encoding in the middle. I tried all the possible ways like changing transitions, restarting my laptop, etc. It did work in AME however my after effects crashed twice. And the AE window looked something like this:-

Neither the composition showed the media nor the preview panel. I tried every possible way I know to get the preview panel back ( restart laptop, restart the app, clear cache, there was no update for driver etc.)
My laptop is Windows 10 (Lenovo).
This project took me 9 hours PLEASE HELP ME ASAP!
