I am using Python to convert CSV files to xlsx files. It works well when I am dealing with smaller files, but when I am dealing with larger files, it will prompt “1073741819 (0xC000000 5)”

I have tried different versions of Python and different libraries, but all have the same results. I tried using a VM virtual machine to create a new system to run the code, but the problem persisted.
At the same time, I also noticed a Python crash warning in the system log. Every time I receive “1073741819 (0xC000000 5)”, I can see an error message in the system log

It’s strange that I’m running the same code on my laptop, it works well, and there’s no problem with the large files, so I’m starting to suspect that my device might be malfunctioning, and I’m confused. I’m using I9-13900K and DDR5. I don’t know if anyone here can help me,

This is my code

import csv
from openpyxl import Workbook

def csv_to_xlsx(csv_file, xlsx_file):

    wb = Workbook()
    ws =
    ws.title = "Sheet1"

    with open(csv_file, 'r', newline='', encoding='utf-8') as file:
        reader = csv.reader(file)

        for row in reader:
csv_file_path = 'F:\1.csv'  
xlsx_file_path = 'F:\data.xlsx'  
csv_to_xlsx(csv_file_path, xlsx_file_path)
