To update the driver, you have to check with the manufacturer's site as already mentioned by @Caledon Ken. Don't expect Windows Updates to find it for you. More often than not, it will always tell you: "Windows has determined that the latest driver is already installed...bla...bla", which is not true in most cases.
To another point, if it were related to a hardware issue, it would probably do the same thing when you rolled back to 1803. So, this shouldn't worry you. I think you have a good chance of finding the main reason of your problems with a system diagnostics report.
