Video wont render

Go right back to AE to the timecode provided in the error message. Make sure you have full resolution preview. Try to preview render around the failing timecode and see what it going to happen.

If AE cannot render the video, disable GPU support, purge cache and cross fingers. If it still fails, have a detailed look into your comp and layers and effects used. You are already suspecting the warp effect, so does it render if the effect is turn off?

If it's the warp effect, does it render in half resolution, third or quarter?

As long as AE cannot preview render the video, there is no way to get a clean export. So that's the goal you have to reach.

What warp transition? If this involves some third-party plug-in or specific procedures it could simply not be compatible for genuine technical reasons like competing for resources when using hardware acceleration features such as might be the case with many effects from Sapphire, Boris Continnumm or even Red Giant products or it could simply not recognize the licensing. Either way, nothing to do with the effects settings and something you need to figure out on another level.
