black screen on after effect

Hello,

I’ve had a version of After Effects installed on my computer for some time now, and it has always worked perfectly until a few weeks ago. Since then, a blank black screen has replaced my compositions, regardless of the project I open.

I’ve tried finding solutions on forums, but nothing has worked. I’ve uninstalled almost all of my software to avoid compatibility issues, changed versions of After Effects, reinstalled new drivers for my graphics card and processor… but still nothing.

I’ve restarted the software while resetting my preferences and even launched it in safe mode with Ctrl+Shift+Alt, but no improvement. Finally, I’ve tried changing the preview settings by toggling between Mercury GPU/CPU settings, but still no success.

I’m quite worried as I can’t seem to find a solution. If it helps, I’ve noticed that when I enable “full screen” in the preview settings, I experience significant display bugs but still no visual output of my scenes.

If you know of a solution, I’d greatly appreciate your help.
This software is incredibly important for my studies, and I can’t afford to continue without it.

Wishing you happy holidays,
Best regards

Before it gets suggested, I’ve already made sure the preview eye icon is enabled in my settings.
