Cannot use any fonts including system fonts

[Jefferson Villasan Josol]

This is the complete command line I've used

ffmpeg -y -i "/storage/0040-18A0/Music Videos on YouTube/TO be synced/ICSM dance.mkv" -c:s copy -q:s 0 -c:a copy -c:d copy -c:v mpeg2video -q:v 0 -map_metadata 0 -vf "scale=1920:-1,colorspace=all=bt2020,ass=/storage/0040-18A0/Music Videos on YouTube/TO be synced/ICSM dance.ass:fontsdir=/system/fonts/DroidSans.ttf" -bufsize 960M -maxrate 480M -r:v 30 -r:a 30 -t 30 -movflags +write_colr "/storage/0040-18A0/Music Videos on YouTube/TO be synced/30s samples.ts"

This is the input and output says...

Can anyone help me how to use system fonts on ffmpeg Termux? Whatever I try is only giving me DroidSansFallback. Here is another one that ffmpeg says....

[Parsed_ass_2 @ 0xa51dd240] fontselect: ("/system/fonts/DroidSans.ttf", 400, 0) -> /system/fonts/Lohit-Punjabi.ttf, 0, Lohit-Punjabi
[Parsed_ass_2 @ 0xa51dd240] fontselect: (DroidSansChinese, 400, 0) -> /system/fonts/Lohit-Punjabi.ttf, 0, Lohit-Punjabi
[Parsed_ass_2 @ 0xa51dd240] Glyph 0x41 not found, selecting one more font for (DroidSansChinese, 16, 400)
[Parsed_ass_2 @ 0xa51dd240] fontselect: (DroidSansChinese, 400, 0) -> /system/fonts/DroidSansFallback.ttf, 0, DroidSansFallback

This the last ffmpeg says...

frame=  899 fps=1.7 q=0.0 Lsize=   25350kB time=00:00:29.97 bitrate=6927.5kbits/s speed=0.0563x

Thanks in advance for those who can help me!

Please provide the command line you tested together with the complete, uncut console output and provide an input file to make this a valid ticket.
