Why do errors appear after compiling the .EXE, does everything work through the .py file?

Question

Python

Before compiling the file in .exe, everything works as it should, after all the resources are packed through pyinstaller into one file, errors appear in the console:

Exception in Tkinter callback
Traceback (most recent call last):
  File "tkinter\__init__.py", line 1699, in __call__
  File "Label for bach scan v4.py", line 64, in get_bach
  File "Label for bach scan v4.py", line 46, in Ean
  File "site-packages\barcode\base.py", line 68, in save
  File "site-packages\barcode\codex.py", line 261, in render
  File "site-packages\barcode\base.py", line 111, in render
  File "site-packages\barcode\writer.py", line 226, in render

  File "site-packages\PIL\ImageFont.py", line 645, in freetype
  File "site-packages\PIL\ImageFont.py", line 194, in __init__
OSError: cannot open resource

The function where the above errors occur:

def Ean():
    EAN = barcode.get_barcode_class('Code128')
    ean = EAN(str(leather_field.get()), writer=ImageWriter())
    ean.save(tempfile.gettempdir() + "\\barcode", {"module_width":0.25, "module_height":5, "font_size": 10, "text_distance": 3, "quiet_zone": 3})

Answer 1

Stel as not recommended but it works.
Replaced font variable in \Lib\site-packages\barcode\writer.py

#FONT = os.path.join(PATH, 'DejaVuSansMono.ttf')
FONT = "arial.ttf"

Answer 2

Judging by the error, not all resources were packed

Answer 3
