When I apply Film Convert Nitrate On a layer in After Effects 2020, its making the preview black and when i turn off the effect the vision is coming back like how to fix this?

I’m using Adobe After Effects 2020 and running into a serious issue with the FilmConvert Nitrate plugin. Whenever I apply the FilmConvert Nitrate effect to any video layer or adjustment layer, the entire preview/composition window immediately turns completely black. The footage becomes invisible as if the layer is not rendering at all.

The project itself is still active and responsive:

• The layer remains visible in the timeline
• Playback still runs normally
• Audio continues to work
• Other effects work fine
• The footage reappears instantly when I disable or remove the FilmConvert Nitrate effect

The issue only happens when FilmConvert Nitrate is enabled. As soon as I toggle the effect off, the video preview returns to normal with no black screen.
