Sort and Sed commands are causing the model not to train (ERROR 1/OUT is empty)

Peace Be Upon you,
I am training an Arabic model from scratch, reaching about 270,000 epochs in 32 hours, the ERROR is still 1, and the OUT is empty.
The data I used for training is artificial and 100% Arabic, contains no diacritics, is 300 dpi, Times New Roman regular size 18, and I,am sure that the transcription is 100% correct.
How is it that I cannot get anything recognized?

The extracted png/gt.txt files
The training script train.sh
The produced clstm models

My training script:

#!/bin/bash
set -x
set -a
sort -R manifest.txt > /tmp/manifest2.txt
sed 1,100d /tmp/manifest2.txt > train.txt
sed 100q /tmp/manifest2.txt > test.txt

I found the solution, it seems to be a weird problem
I removed these lines from the training script, and the problem was solved:

sort -R manifest.txt > /tmp/manifest2.txt
sed 1,100d /tmp/manifest2.txt > train.txt
sed 100q /tmp/manifest2.txt > test.txt

Therefore, you can run these commands in the terminal, and after they finish executing close the current terminal, then you must open a new terminal and run the training script.
After removing these lines from the training script, and then running the training script again the ERROR was changing and the ALN and OUT contained data.
Somehow sed and sort were causing the model not to train, what a weird problem.
