Hello. I have been unable to connect to iTunes on my Mac for a little while (can't determine when problem started but wasn't that long ago) and have troubleshooted the problem, attacking it from different angles to no avail, per Google search recommendations on error 9039. I am at a total loss and need help resolving.
Running iTunes version 12.9.5.5
Running macOS Mojave version 10.14.5
Late 2016 MacBook Pro
Thank you for your prompt assistance.
See If you see an error in iTunes on your Mac or PC - Apple Support. I cannot find anything specific on your error code, but there may be suggestions that help. Given you cannot reinstall iTunes on Mojave you may need to reinstall the OS instead.

Thank you for the suggestion to reinstall macOS which I finally found the time to do this morning. Alas, it made no difference and still can't log in to iTunes and getting unknown error. 9039 I am now on Mojave 10.14.6. I see that others have been complaining recently of the same problem here. What to do?
I have not installed any third party anti virus software. The router has been rebooted numerous times. Funny thing is that the problem began fairly recently and I had installed Mojave long before. Maybe one of the latest macOS upgrades broke iTunes for many or at least several of us? Is Malwarebytes a safe product? Is it available through the App Store? Thanks again.
Malwarebytes is safe as long as you're downloading from https://www.malwarebytes.com/mac/. It isn't available through the app store as, like any other security product, it needs to operate outside the app store sandbox.

I can't be certain it will work, but it shouldn't hurt to try, apart from taking a little time. See Reinstall macOS - Apple Support.

Thank you but I have gone through this (and much else I found by searching Google) in vain. Do you really think reinstalling Mojave is the answer? If so, how do I go about it? Thanks again.
Do you have any third party anti-virus software installed? Can you rule out malware with Malwarebytes? Have you rebooted your router to eliminate any possible issue with cached addresses?
