Until last night/early this morning there were several updates listed that did not appear to download or install. So, last night I changed my power settings to not shut off for several hours. I then plugged in the charger, left the screen up and went to bed. This morning all the updates had installed. So, you might try doing something like that.
I had looked and looked for someway to force the updates to occur but never found anything. It seemed like there used to be an option to manually "Install Now" but I couldn't find it. So glad these updates finally installed. I didn't like seeing that "Failed Install" message next to about a dozen updates.
I also had the problem, mine update was stuck at 48 %. I researched a bit and found that we have to stop the antivirus and defender. I did the same and update happened. I am happy now. [emoji16][emoji16][emoji16]
