I guess it's because of the pdf file, it might be secured. You can try to use a platform for editing pdf documents to edit and save it again, and maybe it will work. I've never used a pdf unlocker tool before, so I don't know much about that, but you can try to use one if you can find them for free online.

I guess it's because of the pdf file, it might be secured. You can try to use a platform for editing pdf documents like [https://pdfliner.com/|https://pdfliner.com/] to edit it and save it again, and maybe it will work. I've never used a pdf unlocker tool before, so I don't know much about that, but you can try to use one if you can find them for free online. Another way would be to save it in another format, like jpg, and save it as a picture, but if you have many pages, this will take a while, so consider pdf liner as a quicker option.
