Error code 4 (premiere pro)

I have been trying to render my current Adobe project for the last three days. Everytime I try to export, halfway through it stops and pops up with a box stating there was an error with rendering one of the filters used on the video, and something about it having to be returned. The error code was 4. I have tired everythuing online from deleting my media cache, to even redownloading filters, but nothing has worked. This project is very important to me, so if anyone can help, it would be appreciated. Ill leave a reference image down below. 

The image included below is similar to the one I received, except mine said returned filter, then showed what filter couldnt be rendered. Keep in mind I've used this filter in projects in the last month so its not outdated or broken. 

Sorry for Error compiling movie. You can also check this link for more suggestions: https://community.adobe.com/t5/premiere-pro-discussions/faq-fix-error-compiling-movie-errors-in-premiere-pro/m-p/12757295#M395728
