After Effects refuses to render full comp
Hi! Recently I've been working on an After Effects CC 2019 project. These are my composition settings:

As there is no longer the H.264 codec embedded into the Render Queue in CC 2019 I have been using Adobe Media Encoder CC 2019 to attempt to render my composition. After trying about 4 times I continued to receive the same popup TextEdit message every time the rendering fails.

The full contents of the TextEdit message reads:
- Encoding Time: 00:18:53

I am not sure what to do anymore. I have updated my After Effects program and tried to change a few effects just to make sure it wasn't too heavy to render but nothing seems to be working. The effects used in the specific time (16:21) is a squeeze warp effect and a camera lens blur effect.
If I could get an answer as soon as possible that would be amazing. Thank you for your time!
