I was trying to fix the msstore path because one package wouldn't install. I've tried the steps in #4785, #4676 and #3303. None of them worked. I accidentally removed the msstore from the sources list and tried to add it back to my discovery of this.

Could you try winget source reset?

PS C:\ManVal> winget source reset
The following sources will be reset if the --force option is given:

msstore https://storeedgefd.dsx.mp.microsoft.com/v9.0 false
winget  https://cdn.winget.microsoft.com/cache        false

The winget source reset --force command was designed to ensure the default sources "winget" and "msstore" are both reset for client devices. As long as there are no Group Policy Objects (GPOs) preventing the addition of unauthorized sources.
