Issue: Error: System.ArgumentException: Illegal character in path

[marticliment]

Issue Description

Sometimes, when calling using gsudo, some users complain about crashes for "illegal characters in path".
The passied command-line arguments, the error seems erratic and not concisely reproducible.

Original Error trace:

Steps to Reproduce

Run gsudo.exe with the following arguments:
"C:\Users\Giesen\AppData\Local\Microsoft\WindowsApps\winget.exe" update --id Tyrrrz.LightBulb --exact --source winget --accept-source-agreements --version "2.5.3" --silent --disable-interactivity --accept-package-agreements --force --include-unknown

It should be noted that gsudo was called from the gsudo.exe directly, started as a process using System.Diagnostics.Process .NET class. The filename is C:\complete\path\to\gsudo.exe, and the arguments
are the ones stated above. The error traceback was captured from STDERR

Screenshots

This is a screenshot of the error shown to the user in my app, which uses gsudo.exe to automate certain tasks.

Context:

• Windows version: Win 11 Pro Build 22631.3810
• gsudo version: gsudo v2.5.1 (Branch.tags-v2.5.1.Sha.25d89fcac99b25534108804cb843fcbebe05a872)
• This issue is possibly the the cause After update to 3.1.0 all winget updates fail marticliment/UniGetUI#2426

Confirming for a similar reason. Recently started using your UniGetUI, started experiencing the same issue you show above but when launching PowerShell (I have the CommandNotFound PowerToys module which uses WinGet on launch) which lead to it crashing almost immediately. Managed to find a temporary fix: ONLY FIXES USERMODE

Change permissions on %TEMP%\WinGet directory to give your user profile Full Access .

Sadly this seems to only work as long as WinGet doesn't get called inside the gsudo elevated environment, which almost completely defeats the point of the fix but it fixes WinGet for anything non-admin
