Windows 10: Whenever I click or switch a tab, my taskbar disappears and reappears, and a loading thing...

This started a day ago, but whenever I click, oftentimes the taskbar suddenly disappears and reappears, and the cursor gets a loading thing. It stops me from clicking on whatever I was clicking, for example, if I was clicking on the search bar, and I can't open the settings anymore due to it. Sometimes the taskbar randomly does that too, even if I don't click. Is there a reason this is happening?

taskbar icons disappear and then reappear

That could mean there was a change detected which needed to be handled by all your active tasks.

That suggests that the current focus was most likely on the Desktop (e.g. assuming you have a lot of icons on your Desktop). Please try to be sure that Narrator gets focus on things that you are interested
in. Again, it may be necessary to practise using the tools before you actually need to try to understand something that is less clear.

Good luck

I have expand the tastkbar wider (picture 2) and found that underlined is not disappear but it hiding lower. So I can see underlined if I expand the taskbar!

User assigned icons disappear from Taskbar in Windows 10

With the main account of my system (which is me), all of a sudden icons that I've put on the taskbar has disappeared. Now I can get them back by dragging and icon to the taskbar and they all reappear, but I really don't want to do that every time. I have
created a second account, logged into it and loaded up the taskbar with icons. Rebooted my system and logged in with the new account and everything works fine.

Their is another post asking this same question. I've followed every step that a gentleman has suggested and nothing works. Has anyone figured this out yet?
