Trouble saving files after i have made comments/highlighted some text

[Albert33818519v3ws]

I have used this program (Adobe Acrobat Reader) for months for taking notes for my study, but suddenly i get this message when i try to save a document, and it just gets blank.

The error message is (roughly translated to english):
"The document couldn't be filed (or archived). The file may be read-only, or another user may be accessing it. Save the document under another file name or in another folder". It doesn't appear read-only though, as i can edit it for a certain amount of time before the problem arises.

If i then try to do one of the options, it says:
"The document couldnt be filed (or archived). Wrong parameter."

Have any of you tried this before? how do you fix it?

Could you post screenshots of the messages?

What is your exact Acrobat Reader version and what is your OS and version.

Acrobat reader is 2023.003.20284 and i have OS Monterey 12.6

I can post a screenshot, but it is in danish, so i don't know how much sense it makes.

Thanks for helping me out!
