Preview, timeline and Export error

Hi everyone,

For about a month now, some of my projects have been generating errors when exporting, playing slides from the timeline, or previewing. Specifically, when I launch a preview, the slide appears completely black (although I can still see the slide names and player). The same issue occurs when I publish the projects.

This problem seems random and only affects me—if I share the project with this error to my colleagues, they can preview and export it without any issues.

I've already tried uninstalling Storyline and restarting my laptop before reinstalling it, but the issue persists.

Can anyone help? It's getting really difficult to work without being able to see what I’m doing! :)
