PDF Error "There was an error opening this document. The root object is missing or invalid"

We use a DB that creates PDF reports when prompted (button that runs a script). There are 4 users of the same DB, 2 of them have no issue at all, and the other 2, when generating the PDF, the file is created (has a normal size compared to the ones created normally), but when opening pops an error message "There was an error opening this document. The root object is missing or invalid" and the file doesn't open with acrobat dc pro or acrobat dc reader (with google chrome it opens a blank page). I tried restarting the computer and the first report I create goes fine, opens normally, but when trying again the issue comes back until next computer restart. Tried reinstalling FMP, Acrobat DC pro and Acrobat DC reader, but the behaviour is the same.
