Unable to install or uninstall Photoshop (Mac OSX, Mojave)

MacOSX Mojave (10.14.1) user on an iMac (21.5in, Late 2013, Intel i7 3.1GHz) - So, this began with me attempting to update Photoshop CC 18 to CC 20, but on every attempt the installer would hang around 82%, for hours, even days, using the CC Installer. Even if trying to cancel the install, the installer would only say "Cancelling" and a reboot would be needed to actually get anything to happen. I followed the support links for manually downloading a copy of Photoshop CC but was only provided a copy of CC 19. Using that lead to it also hanging at around 87%. Several attempts to uninstall were attempted, per the support forums, which also would make it to, around 82% then proceed to do nothing for hours - even as the status would say <1 minute remaining. This was even left overnight, to no avail.

The Creative Cloud Uninstaller was downloaded, and attempted, as per the forums, with the result being roughly the same. Then the Creative Cloud Cleaner was attempted. The CC Cleaner would only crash on trying to "clean" Photoshop, with the MacOS beach ball spinning and the application showing as crashed in Activity Monitor.

Two attempts were made to reach support at this time, but chat is closed and the phone number leads to a hold queue that slowly degraded in phone quality until the hold music would cut off and then the call was disconnected.

Adobe LogCollector was then downloaded per the support forums suggestions (AdobeLogs_20181212_104514_EC7521D6-6610-435C-94E7-AE0706C9096A-mac.zxp), and was sent.

In desperation, the Adobe Photoshop files in the Application folder were deleted manual, as well as deleting the whole of the /Library/Application Support/Adobe folders, and flashing the system PRAM - and trying reinstalls, the CC Cleaner, and a variety of other previously mentioned actions - but none of these have done anything to fix the hanging install issues, at the same percentages.

Short of reinstalling OS X, is there any way I can fix this? Please advise.
