Premiere Pro -Media Encoder Error

Hi 

I am having a problem when trying to export an after effects video. It is giving 'render error' along with this message:

I have tried multiple different export setting, changing to just Mercury Playback Engine Software Only etc but none of the usual fixes seem to be working.

The video doesnt have large assets included to cause the GPU to struggle so I dont think upgrading the GPU resolve this problem.

Some help would be greatly appreciated,

Thanks,

Paul
