Mouse scrolls uncontrollably

Question

A few days ago my mouse starting scrolling drop-down menus on its own.  I have also discovered it will sometimes scroll the left panel in file explorer and on some menus such as the Programs and Features application list.  I've now noticed that drop-down boxes will only flash open making them unusable.  I did not change any setting before this issue started.  I have confirmed the settings are identical to the settings on computers that do not have this issue.

The is not a hardware issue; this is not a driver issue (yes I checked for updates, yes I uninstalled, yes I reinstalled); everything worked fine for a year on this computer until the last few days; I suspect a Windows 10 update caused this; I have tried to uninstall the recent updates, but one of them will not uninstall (KB4577670); this did not solve the problem, nor did reinstalling those updates (KB4576754, KB4580980, KB4577671).

I have tried several mice, both wired and bluetooth with these same results; additionally, these mice work fine on other computers.  The main mouse is a Logitech MX Vertical with 3 bluetooth connections; it works fine on the other two machines it is connected to.  I changed no settings from when the scroll worked fine for a year until it just acted up.

I have tried a few of the other suggestions when making mouse scrolling issue searches and these do not solve the problem.

I run an AMD if that contributes?

Same issue with MX Vertical. Scrolls down a bit and then doesn't want to scroll for a minute or so. Middleclick works fine, scrolling by other mice works fine (g602 is working normally). I haven't tried another machine but I expect its fine too.

Basically it made scrolling not work 99% of the time. So its a pretty terrible update somewhere.
