Another alternative is to set the root_path which fixes the problem both for templates and static folders.

root_path = Path(sys.executable).parent if getattr(sys, 'frozen', False) else Path(__file__).parent

ENV = jinja2.Environment(loader=jinja2.FileSystemLoader(str(root_path / 'templates')))
template = ENV.get_template(your_template_name)
