Failed FLV RTMP streaming to remote source

[adobez]

Summary of the bug: FFmpeg encounters an error when streaming FLV to RTMP after approximately 1 minute and 40 seconds. The error message suggests an issue with submitting a packet to the muxer.
How to reproduce:

% ffmpeg -stream_loop -1 -re -i input.mp4 -r 24
-c:v libx264 -preset ultrafast -b:v 1200k -maxrate 1500k -bufsize 3000k
-c:a aac -b:a 128k -ar 44100 -ac 2
-map 0:v:0 -map 0:a:0 -flvflags no_duration_filesize -max_muxing_queue_size 4096
-f flv "rtmp://live-api.shopee.co.th/live/stream_key"
ffmpeg version: ffmpeg version N-118457-gd6a364e7c3-20250210 Copyright (c) 2000-2025 the FFmpeg developers

Please provide the command line you tested together with the complete, uncut console output to make this a valid question.
