Windows 10: File and Folder autocomplete stopped working

Hi there!
Crossposted here: https://eileenslounge.com/viewtopic.php?f=55&t=31584

I have a very annoying problem in my Windows 10 system: File and Folder autocomplete has stopped working. I am sure I did not make any changes to settings with this regards. In fact I checked all Autocomplete settings and they are fine (see screenshots below):

:)

 

How do I remove an address in the autocomplete list in the Windows 10 mail app?

Folder does not exist.

C:\Users\UserName\AppData\Local\Packages\Microsoft.Windowscommunicationsapps_8wekyb3d8bbwe\LocalState\Indexed

Folder only has this file in it;

_sessionState.dat

And no other folders

Do you want me to delete this file?

autocomplete list in windows 10 mail app

How do I remove an address in the autocomplete list in the Windows 10 mail app? I have a name that appears in the autocomplete list that I don't see in my Peoples app; thus I'm not able to delete the name by going to the Peoples app. The suggested autocomplete
address is no longer an active address thus I would like it removed from the autocomplete list.
