Windows 10: What does this red X mean?

I just did a Clean Install and restored some files and folders from my data drive. This is first time I've ever seen these red Xs and don't know what they indicate. I also see them in File Explorer. Thank you.

Red x icon meaning

Hi,

I am Sumit, an Independent Advisor and a 2-Year Windows Insider MVP here to help.

Red X usually means the device is disconnected. Do you see it on the internet icon?

 

what does the red X on the outlook icon mean?

the Outlook icon on my taskbar has a red X on it. It didn't have it yesterday and the outlook app appears to be working ok. Can anyone explain what the red X means? TIA

 

what does red x mean in file explorer?

I just purchased a new laptop with presumably latest Windows 10. Working through some stuff I now see red circles with an "X" inserted by some File Explorer folders - some very important like "Documents". I tried restarting File Explorer and rebooting the computer but the symbols remain. Also, trying to access some files that I thought were saved are missing. Maybe I didn't actually save them or maybe there's another problem like trying to save to an "X"d folder.

What do these troubling symbols mean and how can I return to a clean File Explorer?

ADDED LATER:

Still looking for a solution I found here that the problem may be related to MSFT One Drive, which I was working with when the problem surfaced. As far as I can tell from the help, the "sync" operation is working. One Drive works okay on my desktop machine and no red x has ever shown previously or now.

Then, I see that the avast antivirus program may use a red x? see the screen capture. but Avast says no threats. Also, McAfee came preloaded on this new laptop and I'm unfamiliar with it's notifications and maybe the red x means that Avast is not working because McAfee is??

just some more clues.....
