BUG: Media Encoder fails at timestamp 00:00:00 (Selector: 9 Error Code: 3) for very long project

After editing a 12h01m long project and trying to render it, after 5 hours of processing Media Encoder reports an error and fails to encode the mp4 file.

This is the error that I get in the logs:

------------------------------------------------------------
 - Encoding Time: 04:57:40
06/09/2024 02:23:39 AM : Encoding Failed
------------------------------------------------------------
A low-level exception occurred in: H.264 (Exporter:9)

Export Error
Error compiling movie.

Export Error

A low-level exception occurred.

Writing with exporter: H.264
Writing to file: D:\main.mp4
Around timecode: 00:00:00:00
Component: H.264 of type Exporter
Selector: 9
Error code: 3

------------------------------------------------------------

I noticed that the timecode is 00:00:00:00, so I ran a test and rendered only the first 30 seconds of the project instead of rendering all 12 hours. Media Encoder rendered everything, and the exported video was fine. So there's nothing wrong with the project at the timecode of 00:00:00:00.

So why is Media Encoder reporting this problem at this timecode then?
What does the "Selector: 9 Error Code: 3" mean?
