WinGet does not work when deployed through Lansweeper

Brief description of your issue

I work at a large organization and we are trying to automate the process of updating apps using WinGet and Lansweeper.

I wrote a script that uses 'winget export' to save a JSON of the installed apps on the device, and compares that to an approved_apps.json file that has the version number we want the apps to update to. When I am logged in as an administrator, the script runs with no issues.

However, when I try to deploy the script through Lansweeper, it fails to export the JSON file. Additionally, I keep getting this error message: "Failed to open available source: winget". I have tried to deploy the script using "system account" and "scanning credentials" on Lansweeper and in both instances it fails. I have also tried to specify the proxy as well but it still fails.

I re-wrote the script without using winget export, but I run into the same issue because of this error "Failed to open available source: winget". When deployed through lansweeper, I keep getting the error message that "[AppID] Not installed."

Steps to reproduce

winget export -o "c:\WinGet Logs\packages.json" --include-versions --accept-source-agreements

Expected behavior

The expected behaviour is that winget successfully exports the packages.json file and does not run into the "Failed to open available source: winget" issue.

Actual behavior

packages.json is not being exported. Failed to open available source: winget

Start by comparing the provided winget export command and attached log when run interactively versus through Lansweeper's system account or scanning credentials. Investigate the Failed to open available source: winget path and the missing IndexDB entry; done means the deployment context can export packages.json without that source error.
