Tesseract5-OCR Train - Segmentation fault error

Question

I am trying to train tesseract 5 on a new font. Am running tesseract on WSL Ubuntu and I followed tutorial by Gabriel Garcia and the official tesseract Compilation docs. Am trying to train tesseract on top of the eng.traineddata file from tessdata_best which i included in the tesseract/tessdata directory. I have also provided the training data (tif, box, gt files) in the tesstrain/data/$(MODEL_NAME)-ground-truth directory.

When i run the train command

TESSDATA_PREFIX=../tesseract/tessdata make training MODEL_NAME=eng START_MODEL=eng TESSDATA=../tesseract/tessdata MAX_ITERATIONS=100

i get the following results

I tried manually adding a path to an lstm file in the list.train file. the error

Failed to load list of training filenames from data/Calibri/list.train 

the above error stopped and when i run the train command again I now got this error

I've search the internet and the closest thing I found was this issue that was opened on the tesseract github page. The issue raised in this post fixed by changing the traineddata file from a fast traineddata to best traineddata. but this did not work for me.

Thanks in advance
