Hi, Zel. I don't think it is your computer specs. That being said, there is no JAWS 19. They stopped designating JAWS versions with two-digit version numbers with JAWS 18. The next JAWS version was JAWS 2019. We are now at JAWS 2021. Have you tried installing JAWS 2021 in demo mode, and checking if JAWS still crashes in your large documents. With all the changes made to Windows 10 in the last two years, as well as the changes to Office, it would not surprise me if portions of it are far enough out of date that JAWS might crash while running Office, especially if it is Office 365. My recommendation to you is to try JAWS 2021, even if you don't have a licence for it. That way, you can rule out an out-of-date version of JAWS being responsible for the problem you are having.
