You didn’t read my followup post yet.
I asked if you tried the uninstall of the last update while in Safe mode?
Sorry, Wuli. I'm busy chasing up so many suggestions that I'm becoming lost. I'll try it and get back to you.
I'm having trouble even locating the list of installed updates prior to September 2019. Maybe I've already deleted them without knowing it.
Man, my brain aches...
