Define the problem: Fonts become italicized system-wide after uninstalling a brand new Maui in .Net 9 app via InstallShield. Explain the goal: To uninstall the application without altering system fonts. Steps: 1.I create a brand new MAUI app in .Net 9. 2.I create setup using InstallShield. 3.I install the setup successfully. 4.I uninstall the setup from control panel. 5.The app removed from control panel,but the fonts in the computer italicized. 6.I install the setup again and fonts become normal. 7.I tested both on Windows 10 and server 2019. 8.The problem not happened when creating a brand new app with WPF.

How this problem can be solved? Thanks,
