Very not happy that GIMP 2.10x insists on uninstalling 2.8x and then use the user folder for 2.8 for itself. This practice needs to end; GIMP 2.10x should install in it's own folder and use another GIMP customization folder. Since, as I suspected, got a heck of a lot of errors due to incompatible plugins, I completely uninstalled 2.10x, deleted the customize folder, copied a backup (smart I was this time) and reinstalled GIMP 2.8.22. Funny thing is, GIMP 2.8.22 now runs a 3rd faster; don't notice anything missing yet, but I suspect I might have lost something (since why is GIMP so spiffy?). lol
I'll wait until the developers address keeping older versions of GIMP intact before I do this exercise again; may look at samj's portable version if she's released it yet in the meantime. Don't usually like portable versions, but I guess I have no choice. I even tried to do a customized install, but the install would not let me choose another folder other than the previous GIMP; not happy about that.
And yes, I took my New Years Day holiday today (since I needed the day off to play in a concert which has now done), so Happy New Years to you all. lol
