if os.path.exists(f'{filename_without_space_main}.{language_code1}.srt'): 
        with open(f'{filename_without_space_main}.{language_code1}.srt', 'r', encoding='UTF-8') as srt_file:
    elif os.path.exists(f'{filename_without_space_main}.{language_code2}.srt'):
        with open(f'{filename_without_space_main}.{language_code2}.srt', 'r', encoding='UTF-8') as srt_file:
    else:
        continue

    srt_file_lines = srt_file.read()

要把读取文件的操作移到 with 语句里面，否则 with 语句的缩进里没有代码，是不符合 python 语法的

if os.path.exists(f'{filename_without_space_main}.{language_code1}.srt'): 
    with open(f'{filename_without_space_main}.{language_code1}.srt', 'r', encoding='UTF-8') as srt_file:
        srt_file_lines = srt_file.read()
elif os.path.exists(f'{filename_without_space_main}.{language_code2}.srt'):
    with open(f'{filename_without_space_main}.{language_code2}.srt', 'r', encoding='UTF-8') as srt_file:
        srt_file_lines = srt_file.read()
else:
    continue
