HELP - Quill Render Error: When I render colored animation it glitches and only renders black

[nomnomdoom]

I'm working in Quill for my animated thesis project and suddenly every file I own only renders black.

The animation timeline works fine. The render previews looks perfect. But the MP4/ PNG files glitch like this.

I have tried:

Uninstalling and reinstalling Quill

Changing the in-scene cameras

Various different rendering options, low medium high quality

Saving in other file locations

Trying other project files, they all render this same way

Asking for some assistance ASAP
