Hi, please try this and let me know if it works: https://github.com/almenscorner/IntuneCD/wiki/FAQ#q-i-get-a-codec-cant-encode-character--when-running-the-backup

Same goes for builtin PowerShell Intune script "Modern Workplace - Autopatch Client Setup v1.1" that is being created automatically when Autopatch feature is used.
