How to fix file not opening when retrieving its path from a file

Question

My program stores its configuration in a text file and retrieves it when you restart the program. When I first enter the configuration, it works, but when I restart the program it suddenly stops working. Any help is appreciated
Full code:

import os

datainfile = []

if os.path.isfile("config.txt"):

    cfg.close()
    a = datainfile[0]
else:
    cfg = open("config.txt", "w")

    cfg.write(a+"n")
    cfg.close()

os.system('"%s"' % a)

Before restarting:

After restarting and pressing the button:
