Render fails, no error message
I'm having an issue rendering a project. The whole project is only 8 seconds long.
There is no message error that comes up, I just hear that annoying sheep sound. It does say "Failed 00;06;02" every time. At 06;02, I used the Warp effect but I made sure the motion tile is at 200. Usually when it's an error with the Warp effect, an error message pops up and tells me that.
Here are my render settings:

I like to use H.264 because I've noticed it really improves the quality.
I only have 8 GB of memory. I know, not a lot, but for the most part, my videos always render without issue.
I'm using an external hard drive with 1 TB.
The whole project is only 8 seconds long and there aren't any more effects than I usually use. I used the Twitch plugin and I've heard that that can be the issue, but everytime I've used Twitch in the past, it's rendered correctly. Also, everytime I try prerending it fails too.

If you know anything about this, please let me know!
