Why i can't render 4K video

[ujjally]

I can't render 4k size video or clip. Technically 1441p to 2160p height of video/clip. I am getting the below error.

###The error start###

Moviepy - Building video 4k-2160.mp4.
MoviePy - Writing audio in 4k-2160TEMP_MPY_wvf_snd.mp3
MoviePy - Done.
Moviepy - Writing video 4k-2160.mp4

###The error end###

###My System###
CPU: 1core
RAM: 3GB
Disk: 100GB
OS: Linux/Debian
FFmpeg: 7:4.3.5-0+deb11u1
Python3: 3.9.2-3

Also, i tried to edit moviepy > config_defaults.py like this but got the error when rendering 4k video.
FFMPEG_BINARY = os.getenv('FFMPEG_BINARY', '/usr/bin/ffmpeg')
IMAGEMAGICK_BINARY = os.getenv('IMAGEMAGICK_BINARY', '/usr/bin/convert')

When rendering below 4k video, it works fine.
