Windows 10: Windows 11 update KB5053656 lowers monitor brightness

This update seems to have a bug. When I reboot my desktop after the installation, I find the brightness level of my LG monitor has been darkened not completely black, just darker. It's not a personalization setting issue--the illumination of all images on the computer darker. I've tried installing and uninstalling the update twice and it's always the same results. Why is this specific update doing this to the brightness of my monitor? If there is no solution, then please tell me how I can block any further installations of this specific update.
