When I try to download or manually pack, it says "downloading" or "packing" at the top, but the progress bar doesn't move at all, and I never get the file

Also, when I look at the script in tampermonkey, it says, there are 15 bugs or clues found

Which browser do you use ? Can you tell me the version of your browser ?
And can you offer error details

1. I use Google Chrome
2. The newest version
3. The first two errors appear once, the rest multiple times. The errors "curly - Expected" appear for "if", "for" and "else".
