I have uninstalled Zygor and will reinstall with fresh copy. If i continue to get these errors I will have to remove Zygor and drop my subscription.

Other note: I have not seen any upgrades to zygor pertaining to made available to classic much like retail in a very long time.. Have yet to see the dungeon viewer map option, and the zygor gold trend is never accurate with any scans of the auction house..

Try doing a full guide reset.

1. exit WoW
2. go to the WoW/_classic_/Interface/Addons folder and delete the ZygorGuidesViewerClassic folder
3. go to the WoW/_classic_/WTF/Account/<your account name here>/SavedVariables folder and delete the Zygor files in there
4. run the desktop client and install a fresh copy of the guides
5. go back in game to test and let me know if that fixed it

When it comes to retail, the time between the last major patch (8.3) and the next expansion are always very sparse for updates.
