Windows 10: KB5018410 update makes my taskbar very slow

After I installed the KB5018410 update even the subsequent 22H2 update, there was a 500ms blank time per click to show the hidden icon. After uninstalling the update it worked fine. What caused it?

cumulative updates fail to install. Both KB5018410 and KB5016616 failed on installation.

My computer is a DELL Optiplex 3020. Both recent cumulative updates (KB5018410 and KB5016616) have failed on installation. The code is 0x800f0845. I have tried all the suggested things to try to get the update to go through up to an in-place update. All other updates go through with no problem. Just the cumulative updates. I have version 21H2 build 19044.1826.
