Description
Hello I am currently getting the error:
"Failed to open the predefined source; please report to winget maintainers.
An unexpected error occurred while executing the command:
0x800700b7 : Cannot create a file when that file already exists."
When trying to use winget. I have tried to install the latest dev build but that has not solved the issue. I tried a few different steps found in other posts such as updating sources but no go. This error is on my work computer running normal build of win 11.
Oddly I'm also having issues with winget on my home PC with win 11 beta ring but that error says the following:
"Failed when searching source: msstore
An unexpected error occurred while executing the command:
0x8a150044 : The rest source endpoint is not found."
I can make two separate posts if that is better.

Research direction
Start by reproducing the reported winget source failures on Windows 11, focusing separately on the predefined source and the msstore source. Compare the two reported error codes and the attempted source-update steps; done means identifying a reproducible cause and a confirmed fix or clearly scoped follow-up.
