Ошибка в скомпилированном файле Python

Код работает без ошибок в IDE. Но после компиляции и запуска, появляется ошибка:

[ WARN:[email protected]] global D:\a\opencv-python\opencv-python\opencv\modules\imgcodecs\src\loadsave.cpp (239) cv::findDecoder imread_('A:\Python\PR\output\progres_bar.png'): can't open/read file: check file path/integrity

OSError: Failed to read A:\Python\PR\output\progres_bar.png because file is missing, has improper permissions, or is an unsupported or invalid format

Компилирую через auto-py-to-exe. Команда для компиляцию выглядит так:

pyinstaller --noconfirm --onefile --console --add-data "A:/Python/PR/progres_bar.png;." --add-data "A:/Python/PR/ui.py;." --add-data "A:/Python/PR/v3.py;."  "A:/Python/PR/main.py"

В коде путь к файлу прописан вот так:

def resource_path(relative_path):
    try:
        base_path = sys._MEIPASS
    except Exception:
        base_path = os.path.abspath(".")
    return os.path.join(base_path, relative_path)

progres_bar_img = resource_path("progres_bar.png")
