Hi Aisyah,
This usually happens when the hyperlink points to a page number instead of a bookmark or heading. Word automatically repaginates documents whenever content, margins, fonts, or printer settings change, so page numbers can shift after you reopen the document.
If the link is intended to navigate within the same document, I'd recommend:
Insert a Bookmark (Insert → Bookmark) at the target location and link to the bookmark instead of a page.
If you're using headings, link to the Heading rather than a page reference.
Press Ctrl+A, then F9 to update all fields before saving the document.
If you're using a Table of Contents or cross-references, update those fields as well before closing the file.
