After effects not exporting or playing back last 3 seconds of any video when I include a music track

Hi everyone,

I have been experiencing issues the last week with my after effects videos. They are all different and all have different content but when I apply a sound track in any format they all fail to render / play back the last 3 seconds. When I export the video without sound its fine and I have tried putting both the sound and video into premiere pro and still crashes with the last 3 seconds.

I have updated my after effects version to the lastest one, reset all preferances, cleared caches, checked my video and sound settings match what is being output and checked there are no faults with any expressions. 

Do you have any idea why its crashing the last 3 seconds of any video?

Thanks,
Nicole
