Problems with file pyinstaller

[python-and-cabbage]

I tried writing a piece of code

import fitz # pymupdf

doc = fitz.open("111.pdf")
new_pdf = fitz.open()
for page_num in range(doc.page_count):
    page = doc[page_num]
    rect_1 = fitz.Rect(10, 10, 2000, 20)
    page.insert_htmlbox(rect_1, r'hello word', css="* {font-family: sans-serif;font-size:10px;}")

new_pdf.insert_pdf(doc, from_page=0, to_page=page_num)
new_pdf.save('123.pdf')
new_pdf.close()
doc.close()

Works fine in pycharm.

Packaged via pyinstaller.

pyinstaller --onefile --windowed  --noconsole --icon=app_icon.ico --hidden-import fitzter test1.py

error
