MySQL v8.0.19 -> 8.0.41 upgrade failed

[Reyna Hollinshead]

Howdy folks. I am remediating security vulnerabilities by applying & updating the newest set of CPUs to a number of MySQL instances to bring them to the newest version

My other attempts succeeded with ease but I have one problem child that I could use help with

Scenario is that the binaries upgrade to 8.0.41 has already completed successfully but the system table upgrade step remains unfinished.

The failure is reliably reproduceable. Process is:
1) Launch MySQL Commercial Installer from start menu, using version 8.0.41.0 from Oracle MOS which is patch ID 37499809. No impact if I specifically elevate the installer with admin privs

2) See the list of installed products. I'm clicking 'reconfigure' to get back into the system table upgrade portion, click next, click execute to begin.

Failure is assured here, but the Log shows 1 of 2 outputs:
1) First it fails to continue past the 'Attempting to start service MySQL80...' and will time out here ad infinitum regardless of how much time lapses

2) Secondly, if I begin executing the upgrade while the MySQL windows service is stopped, the upgrade will begin normally. It appears to continue just fine but then fails to complete with errors


My REAL problem here is that I cannot identify any clues or breadcrumbs about what the actual error is that's stopping the upgrade. Admittedly I am not very familiar with MySQL so I'm hoping this is down to my inexperience on not knowing where to look, but I don't see any errors logged out to the Application or System views of Event Viewer nor does anything stand out in the log from "C:\ProgramData\MySQL\MySQL Installer for Windows\Logs\"

Here is the output that is shown from the log
